Bug #15081

Upgrade fails due to undersized EFI filesystem
0%
Description
Some installations as recent as Plus 22.01 / CE 2.6.0 have EFI partitions that were created and/or populated by the old EFIFAT image method. This means that while the EFI partition is 200M, the EFI filesystem is only around 700KB. As a result, these installations are unable to upgrade to recent versions successfully as the loader cannot be updated.
This can be worked around by reformatting the EFI partition directly and copying the appropriate files back into place, as described in this forum post: https://forum.netgate.com/post/1140955
# mkdir -p /boot/efi
# mount_msdosfs /dev/msdosfs/EFISYS /boot/efi
# mkdir -p /tmp/efitmp
# cp -Rp /boot/efi/* /tmp/efitmp
# umount /boot/efi
# newfs_msdos -F 32 -c 1 -L EFISYS /dev/msdosfs/EFISYS
# mount_msdosfs /dev/msdosfs/EFISYS /boot/efi
# cp -Rp /tmp/efitmp/* /boot/efi/
There are some potential complications there. For example, the EFI filesystem may not be labeled that way, it could be /dev/gpt/EFISYS or it may have no label at all.
Marked as Plus 24.03/CE 2.8.0 but if it can be fixed in the pfSense-boot package the fix could be picked back to 23.09.1/2.7.2.

Do old efifat images match well-known hashes? If so, look for a partition matching the hash (maybe a bunch of different hashes for recent/upgrade-supported releases) and do the workaround on it. If none is found accept a failure pointing users to this issue. If this fits the vast majority of installations it could be acceptable.

Moving this ahead as it still might be an issue though it's unclear how many affected systems may be left in the wild. I've tried installing versions as far back as 21.02 and they all had properly sized EFI filesystems, so we also are still investigating the exact circumstances around when/how these systems may have ended up in the problem state.
