@Woodrow thanks for your changes - you are right the binaries are already included by hooks from dependencies. LGTM from my side - although I cannot review formally apparently :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881074 Title: Support btrfs when writable is converted to btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools-devices/+bug/1881074/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've revised it accordingly.

Finally, you will need to use copy_exec for btrfs and blkid to the

I think it should be fine here.
blkid is indeed included by udev's hook as udev is also one of dependencies
for initramfs-tools-core.
Thanks,
Woodrow
Otherwise, looks good to me.

[Bug 1881074] Re: Support btrfs when writable is converted to btrfs
Some comments on the debdiff:
Use
blkid -s TYPE "$writable_part" -o value
instead of
blkid -s TYPE "$writable_part" | awk '{print $2}' | grep -o '".*"' | tr -d '"'
No need to redirect to >>$LOGFILE in resize_filesystem() which is
already redirected when called. Also, you should not redirect to
/dev/kmsg - I guess that was for debugging purposes.
Is it really necessary to mount the partition to find out the filesystem usage?
"btrfs filesystem show" apparently can work on devices according to [1]. But it
also looks like btrfs commands are mostly used with mounted systems, so it is
fine if you want to keep things like that.
Finally, you will need to use copy_exec for btrfs and blkid to the
fixtrtc hook to get them included in the initramfs (although maybe blkid
comes from busybox in this case, not sure).
Otherwise, looks good to me.
