execvp() in the child branch of a vfork(). Changed to use fork()
instead.
Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

it if flags were explicitly specified on the command line. Do not warn
if we were merely trying to preserve flags or remove UF_NODUMP. NFS does
not support flags.
I'm not sure that this is ideal, but it should do for now. Installing
a plain file onto a NFS server must work, we used to silently ignore the
attempt. Doing a binary install looses the flags anyway since cpio
doens't preserve them with the cdrom/network images.
XXX make world should not use flags or chown/chgrp in the obj/tmp area.
This is based on a suggestion from Ken Merry <ken@plutotech.com>.
types. The NetBSD compatibility cruft was more correct for -current
than FreeBSD's own code. It just used NetBSD #defines instead of
string literals for the filesystem names. NetBSD's MOUNT_UFS is
"ffs", so using a literal "ufs" gives wrong results, but this is
unimportant, especially for bootstrapping.
Fixed style bugs in trymmap().
Fixed some disordered declarations.
handy at the moment with -current's mmap+unlink interactions.. The
problems seem worst when using INSTALL="install -C" in /etc/make.conf.
This could well come in handy in the future too.
2) When uid/gid not specified, not try to set 0:0 owner, just do nothing.
It makes possible to use install -d by users without setting
their uid:gid each time.
3) Be more specific where install_dir fails
reopen it after strip has finished. This makes it work when
/usr/bin/strip replaces the file rather than doing an in-place edit
(such as the binutils-2.8 strip, which is a variation of objcopy).
This is necessary if install(1) and strip(1) are going to cooperate
on an ELF system.
until the includes are installed, and it doesn't install the includes until
xinstall is built (the previous xinstall binary may not have -C). As a
bandaid, define MAP_FAILED ourselves if <sys/mman.h> didn't. Perhaps it
would be safer to simply disable mmap if all the prerequisites are not
there.
- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.
- Check for failure where no checks were present.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- Change the debug flag from -d to -D to avoid conflict with other
install programs.
- Update man page to reflect this
- Update usage string
-d meaning creat directory is specifically not implemented by these changes.
copy.
Dont leave stray INS@xxxx temp files around, especially when installing
something less than 8MB and the destination runs out of space, etc.
It still doesn't clean up the temp files on SEGV or other signals etc.
installing. mmap'ing stuff over a nfs mount took out my machine during
a 'make world' last night while I was asleep. I started out with a list
of fs's to avoid, when I realised that I really didn't know which ones
were safe with mmap, so I went for the ones I knew and implemented a
fallback compare.
installs something. This is not 100% right, since it has a false hit
when install -C snaps hard links.
Also, run strip(1) from the $PATH, otherwise you need a special version
of install to install (say) elf binaries which have a different strip.
With JDP's elfkit, the layout of the path determines which binary format
you are generating.
allow the user to install using a Numeric GID or UID.
this brings it in to line with chgrp and chown, ans is required
by some people using FreeBSD in a product.
time of the target if the target file is the same as the source),

Use library err() functions instead of our own and pass them better
exit codes.
