08a75d1f0e Create the arm64/aarch64 VM disk image as MBR instead of
GPT scheme.  UEFI needs to know the unique partition GUID
with GPT, which changes each time.  Specifically, the QEMU
EFI BIOS file has this hard-coded.[1]

Since the GPT labels are now unavailable, unconditionally
label the root filesystem as 'rootfs' with newfs(8), since
it does not hurt anything anywhere else.  For the arm64 case,
'/' is mounted from /dev/ufs/rootfs; for all other VM images,
'/' is mounted from /dev/gpt/rootfs.

Unfortunately, since the /dev/gpt/swapfs label is also lost,
set NOSWAP=1 for the arm64/aarch64 images.  This is temporary,
until I figure out a scalable solution to this.  But, a certain
piece of softare was written "very fast", and ended up living
for 15 years.  We can deal with this for a week or so.

4b8175ee8f When building VM disk images, vm_copy_base() uses tar(1) to
copy the userland from one md(4)-mounted filesystem to a clean
filesystem to prevent remnants of files that were added and
removed from resulting in an unclean filesystem.  When newfs(8)
creates the first filesystem with journaled soft-updates enabled,
the /.sujournal file in the new filesystem cannot be overwritten
by the /.sujournal in the original filesystem.

To avoid this particular error case, do not enable journaled
soft-updates when creating the md(4)-backed filesystems, and
instead use tunefs(8) to enable journaled soft-updates after
the new filesystem is populated in vm_copy_base().

While here, fix a long standing bug where the build environment
/boot files were used by mkimg(1) when creating the VM disk
images by using the files in .OBJDIR.

963412283a Clean up filesystem unmounting in vmimage builds:
* Remove vm_umount_base function which is currently unused.
* Add umount_loop function which loops attempting to unmount one filesystem.
* Replace calls to umount with calls to umount_loop.
* Don't attempt to unmount ${DESTDIR}/dev if it isn't mounted.

The looping is necessary because sometimes umount fails due to filesystems
being busy.  The most common cause of such busyness is periodic(8) jobs
running `find / ...`.

25c1155771 When creating VM images, copy the contents of the created filesystem into
a new filesystem before packaging it into a disk image.  This prevents
"remnants" of deleted files from showing up in the VM images, and reduces
their compressed size (by about 10% for the cloudware images) as a result.

 r273823:
  Move virtual machine / cloud provider targets and
  options from release/Makefile to their own Makefile.

 r273824:
  Add glue to allow enabling building cloud provider VM images
  by default.

  When WITH_CLOUDWARE is not empty, add CLOUDTARGETS to the
  release/Makefile 'release' target.

 r273825:
  Avoid hard-coding the Azure image file format.  While here,
  avoid using OSRELEASE for the output file name.

 r273826:
  Remove a few vestiges of passing an exit code to panic().

 r273833:
  Initial commit providing a mechanism to create openstack images
  as part of the release build.

 r273836:
  Fix output file name for openstack images.  No further conversion
  is necessary for this VM file target, so there is no need to append
  the '.raw' suffix here.

 r273944:
  Uncomment the cloudinit rc.conf(5) line.

 r274069:
  Add line continuation so OPENSTACKCONF is actually included in the env(1).

 r274070:
  Add a 'vm-cloudware' target, used to drive all targets in CLOUDTARGETS.

 r274071:
  Add examples for WITH_CLOUDWARE to release.conf.sample.
  Add WITH_CLOUDWARE evaluation to RELEASE_RMAKEFLAGS.

 r274134:
  Initial rewrite to consolidate VM image build scripts into one.

 r274211:
  Add write_partition_layout() used to populate the final image.

  Fix duplicated mkimg(1) call in vm_create_disk().

  Add primitive (untested) PowerPC/PowerPC64 VM image support.

  Note: As it is currently written, the /boot/pmbr and
  /boot/{gptboot,boot1.hfs} use the build host and not the target
  build.  Fixing this is likely going to be a hack in itself.

 r274280:
  Return if vm_create_disk() is unsuccessful.

 r274281:
  Add CLEANFILES entry for VM targets

 r274282:
  Add vm_extra_pre_umount() prototype to vmimage.subr.

 r274283:
  Fix DESTDIR for installworld, and make sure it is created before use.

 r274284:
  Move usage() from vmimage.subr to mk-vmimage.sh, in case vmimage.subr
  has not been sourced.

 r274285:
  Spell 'OPTARG' correctly.  Actually call vm_create_base().

 r274287:
  Fix line continuation in write_partition_layout().
  Remove variable test that is no longer needed.

 r274288:
  Fix scheme flag to mkimg(1).

 r274292:
  mount(8) and umount(8) devfs(5) as needed.

 r274296:
  Change path for mk-vmimage.sh from ${TARGET}/ to scripts/ now that
  it is consolidated into one file.

  Fix paths for the base image and output disk image files.

 r274297:
  Call cleanup() after everything is done.

 r274356:
  Remove a stray directory from CLEANFILES.

 r274533:
  Set the boot partition type to 'apple-boot' for powerpc.

 r274725:
  In vm_install_base(), copy the host resolv.conf into
  the build chroot before attempting to do anything that
  requires working DNS (i.e., pkg bootstrap).

  In vm_extra_pre_umount(), remove the resolv.conf before
  the disk image is unmounted from the backing md(4).

 r274726 (cperciva):
  Silence errors when umounting the chroot's /dev, since it
  probably doesn't exist when we're running this.

  Unmount filesystems before attempting to destroy the md which
  holds them.

 r274729 (cperciva):
  Unmount filesystem and destroy md before we read the vnode from
  disk and package it into a disk image.  Otherwise we end up
  packaging an unclean filesystem.

 r274734 (cperciva):
  Merge duplicative vm-CLOUDTYPE targets before additional duplication
  gets added by the impending arrival of ec2 and gcloud.

 r274771 (cperciva):
  Add NOSWAP option which can be set by a vmimage.conf file to specify
  that no swap space should be created in the image.  This will be used
  by EC2 builds, since FreeBSD/EC2 allocates swap space on "ephemeral"
  disks which are physically attached to the Xen host node.

 r274945:
  In vm_extra_install_packages(), only bootstrap pkg(8) if
  VM_EXTRA_PACKAGES is empty.

  In vm_extra_pre_umount(), cleanup downloaded packages if pkg(8) was
  bootstrapped earlier.

 r274946:
  Fix indentation nit.

 r277180:
  In vm_extra_install_base(), do not install waagent in the openstack
  image, because it is not used.  This appears to be a copy mistake.

  Remove vm_extra_install_base() from the openstack.conf entirely,
  since it does not need to be overridden.

 r277183:
  Enable the textmode console by default for VM images, since there is
  no way to tell if the environment will be able to use the
  graphics-mode console.

 r277184:
  Enable password-less sudo for openstack images.

 r277186:
  Update the VM_EXTRA_PACKAGES list for the openstack images.

  The documentation suggests doing a "just fetch this and run it"-style
  bootstrap, from which the list of dependencies was obtained (in
  github, at: pellaeon/bsd-cloudinit-installer)

  There is one Python dependency unmet, oslo.config, which is not in
  the Ports Collection.

 r277187:
  Add a comment to note that setting hw.vga.textmode=1 is temporary.

 r277250:
  Remove vm_extra_install_base() for the Azure image, now that the
  waagent exists in the ports tree.

  Add sysutils/azure-agent to the VM_EXTRA_PACKAGES list.

  In vm_extra_pre_umount(), remove the explicit pkg(8) install
  list, as dependencies are resolved by sysutils/azure-agent.

 r277251:
  Add a 'list-cloudware' target to print the list of supported CLOUDWARE
  values and a description.

  Add the AZURE_DESC and OPENSTACK_DESC descriptions.

 r277252:
  Update release(7)

 r277253:
  Add 'list-vmtargets' target, which produces a list of all supported
  VM and cloud provider images.

  Add VHD_DESC, VMDK_DESC, QCOW2_DESC, RAW_DESC image descriptions.

  Format the output to make a bit more readable.

  Update release(7) to document the list-vmtargets target.

 r277263:
  Add initial support for the GCE (Google Compute Engine) cloud hosting
  provider image.

 r277264:
  Style and line length cleanup.

 r277383:
  Remove the console setting from rc.conf(5), which is not used there.
  While here, set console to include vidconsole in the loader.conf(5).

 r277384:
  Fix an indentation nit.
  No functional changes.

 r277393:
  Remove the pkg-clean(8) call from vm_extra_pre_umount() since the
  function is often overridden.

  Add vm_extra_pkg_rmcache() to call pkg-clean(8) to avoid duplicated
  code.

 r277394:
  Move resolv.conf(5) removal back to vm_extra_pre_umount() where it
  belongs.

  The GCE image needs resolv.conf(5) to exist (created as part of the
  image setup), so it cannot be removed.

 r277395:
  Comment the line that configures ttys(5) to 'off', which makes it
  impossible to test that the image boots.

  Add a note explaining why the line is commented, and not (yet) removed
  entirely.

 r277438:
  Move the 'install' bits that are specific to virtual machine images
  from the Makefile to Makefile.vm.

  Rename the 'install' target to 'release-install', and add a new
  'vm-install' target.

  Add a new 'install' target that invokes the new targets.

 r277439:
  Add WITH_CLOUDWARE to the list of make(1) variables for the release
  build.

 r277447:
  Remove hw.vga.textmode=1 from the VM image loader.conf, which was
  included during test builds and not intended to be included when
  merging this project branch back to head.

 r277455:
  Remove mk-azure.sh, which is no longer needed.

32dbc82982 Change how packages are installed into VM images: Rather than chrooting
into the image and running 'pkg install' from there, use 'pkg fetch' to
download packages into a temporary location and then 'pkg add' to install
them into the image.

This simplifies the code by avoiding the need to copy /etc/resolv.conf
into the image and then delete it later, and makes it possible to cross
build (e.g., to create an amd64 image when running on i386 hardware; or
in the future for building disk images for embedded platforms).

Because pkg was implicitly installed when VM_EXTRA_PACKAGES was non-empty,
add it to VM_EXTRA_PACKAGES in azure.conf and openstack.conf to maintain
the current behaviour.

By default repo-FreeBSD.sqlite is copied into the image, (a) to match
previous behaviour, where the file would be downloaded by the chrooted
pkg invocation; and (b) because it may be useful for testing purposes,
e.g., to see why a package didn't get installed.  Because this file is
large (46 MB) and not likely to be useful in -RELEASE images which are
being launched into Clouds several months later, it can be disabled by
setting NOREPOSQLITE.

As far as I know this commit does not change the disk images produced in
any filesystem-visible way.

 - Move amd64/mk-vmimage.sh -> scripts/mk-vmimage.sh.
 - Remove vm-base target from Makefile.vm.
 - In vm-image target, use getopts flags for argument passing.
 - Create tools/vmimage.subr, containing default and prototype
   for the following functions that are used to drive the build,
   run in this order:

   vm_install_base()
   vm_extra_install_base()
   vm_extra_install_packages()
   vm_extra_install_ports()
   vm_extra_enable_services()
   vm_extra_pre_umount()
   vm_create_disk()
   vm_extra_create_disk()

 - In tools/azure.conf, override:

   vm_extra_install_base()
   vm_extra_pre_umount()
   vm_extra_create_disk()

 - In tools/openstack.conf, override:

   vm_extra_install_base()
   vm_extra_pre_umount()
