- Teach gptboot and gptzfsboot about new files. I haven't touched the
rest, but there is still a lot of code duplication to be removed.
- Implement full GPT support. Currently we just read primary header and
partition table and don't care about checksums, etc. After this change we
verify checksums of primary header and primary partition table and if
there is a problem we fall back to backup header and backup partition
table.
- Clean up most messages to use prefix of boot program, so in case of an
error we know where the error comes from, eg.:
gptboot: unable to read primary GPT header
- If we can't boot, print boot prompt only once and not every five
seconds.
- Honour newly added GPT attributes:
bootme - this is bootable partition
bootonce - try to boot from this partition only once
bootfailed - we failed to boot from this partition
- Change boot order of gptboot to the following:
1. Try to boot from all the partitions that have both 'bootme'
and 'bootonce' attributes one by one.
2. Try to boot from all the partitions that have only 'bootme'
attribute one by one.
3. If there are no partitions with 'bootme' attribute, boot from
the first UFS partition.
- The 'bootonce' functionality is implemented in the following way:
1. Walk through all the partitions and when 'bootonce'
attribute is found without 'bootme' attribute, remove
'bootonce' attribute and set 'bootfailed' attribute.
'bootonce' attribute alone means that we tried to boot from
this partition, but boot failed after leaving gptboot and
machine was restarted.
2. Find partition with both 'bootme' and 'bootonce' attributes.
3. Remove 'bootme' attribute.
4. Try to execute /boot/loader or /boot/kernel/kernel from that
partition. If succeeded we stop here.
5. If execution failed, remove 'bootonce' and set 'bootfailed'.
6. Go to 2.
If whole boot succeeded there is new /etc/rc.d/gptboot script coming
that will log all partitions that we failed to boot from (the ones with
'bootfailed' attribute) and will remove this attribute. It will also
find partition with 'bootonce' attribute - this is the partition we
booted from successfully. The script will log success and remove the
attribute.
All the GPT updates we do here goes to both primary and backup GPT if
they are valid. We don't touch headers or partition tables when
checksum doesn't match.

GPT_ENT_ATTR_BOOTME - this is bootable partition

GPT_ENT_ATTR_BOOTFAILED - set this flag if we cannot boot from partition

boot from partition that contains only GPT_ENT_ATTR_BOOTME flag,
the GPT_ENT_ATTR_BOOTFAILED flag won't be set
According to wikipedia Microsoft TechNet says that attributes are divided into
two halves: the lower 4 bytes representing partition independent attributes,
and the upper 4 bytes are partition type dependent. Microsoft is already using
bits 60 (read-only), 62 (hidden) and 63 (do not automount) and I'd like to not
collide with those, so we are using bit 59 (bootme), 58 (bootonce) and 57
(bootfailed).

Large (60GB) filesystems created using "newfs -U -O 1 -b 65536 -f 8192"
show incorrect results from "df" for free and used space when mounted
immediately after creation. fsck on the new filesystem (before ever
mounting it once) gives a "SUMMARY INFORMATION BAD" error in phase 5.
This error hasn't occurred in any runs of fsck immediately after
"newfs -U -b 65536 -f 8192" (leaving out the "-O 1" option).
Solution:
The default UFS1 superblock is located at offset 8K in the filesystem
partition; the default UFS2 superblock is located at offset 64K in
the filesystem partition. For UFS1 filesystems with a blocksize of
64K, the first alternate superblock resides at 64K which is the the
location used for the default UFS2 superblock. By default, the
system first checks for a valid superblock at the default location
for a UFS2 filoesystem. For a UFS1 filesystem with a blocksize of
64K, there is a valid UFS1 superblock at this location. Thus, even
though it is expected to be a backup superblock, the system will
use it as its default superblock. So, we have to ensure that all the
statistcs on usage are correct in this first alternate superblock
as it is the superblock that will actually be used.
While tracking down this problem, another limitation of UFS1 became
evident. For UFS1, the number of inodes per cylinder group is stored
in an int16_t. Thus the maximum number of inodes per cylinder group
is limited to 2^15 - 1. This limit can easily be exceeded for block
sizes of 32K and above. Thus when building UFS1 filesystems, newfs
must limit the number of inodes per cylinder group to 2^15 - 1.
