[PATCH v5 0/1] expand-on-first-boot: Switch from resize2fs to systemd-growfs

[PATCH v5 0/1] expand-on-first-boot: Switch from resize2fs to systemd-growfs

[Tobias Schmidl]

Diff to v1:
- Rewording on patch message ("root partition" --> "last partition",
  added note to systemd-dependency and its impact)
- Added systemd-version dependency
- Removed runtime if case that allowed for non-systemd systems

Diff to v2:
- Version bump to v1.2
- Removed e2fsprogs as dependency

Diff to v3:
- Omit the explicit call to systemd-growfs if a fstab option has been
  found
- Be able to deal with both mounted and unmounted mountpoints

Diff to v4:
- Mount the last partition unconditionally to a tmp dir and let
  systemd-growfs operate there.

[PATCH v5 1/1] expand-on-first-boot: Switch from resize2fs to systemd-growfs

[Tobias Schmidl]

We want to be more versatile in our approach of resizing the last
partition. Therefore we switch from resize2fs to systemd-growfs.

This allows for ext4, btrfs, xfs, and dm-crypt partitions to be resized.

Since systemd-growfs landed in v236, this obsoletes expand-on-first-boot
on stretch (v232).

Cool, seems that "unconditional mount/umount" trick indeed works. LGTM

Only one minor observation that I should have made sooner (so if there are
other changes that might warrant a v6, great, but otherwise I don't think
it's necessary).

This error message may be a bit more helpful if it stated the impact of
this problem.  Something like this, instead:

	echo "Cannot create temporary mount point ${MOUNT_POINT}, ${LAST_PART} will not be resized." >&2

The script failing always has that result. In fact you end up in a
weird state where the partition has been grown and the filesystem has
not. Not sure this is needed.

Joe did you get a chance to try that all on your btrfs use-case? I know
Tobias tested that but getting a confirm that it works in other layers
would be cool. But we do not need such a confirm to continue, we assume
it will work in layers.

That's a good point.  Actually, ideally we would roll back to the previous
(probably consistent) state, but that's going to be a difficult thing to
do safely, for sure!

I did not yet, but I keep intending to, it's just a matter of finding time
to.  Having watched the progression of the work, I would be very surprised
if it does not, but I'll follow up here as soon as I get a chance to
verify this one way or the other.

ich sortiere so diffs immer andersrum, die neuste oben so wie man ein
changelog halt schreibt, ist aber geschmackssache

bei der Serie hättest du Jan mit draufnehmen können, der hat nen review

I've been largely silent on these threads so far but I have been watching
the progress.  This version looks good to me and will work well, I think,
for my longer-term goals as well. The switch to systemd-growfs looks like
the correct future-proof approach, so thanks for that.  :-)

I also prefer to have the 'diff history' comments in a most-recent-first
format, as in changelogs, but since the list here is short it's still easy
to find the relevant information quickly.

Ooops, the "reply-all" while wanting "off-list" mistake again ;)

At least i did not say anything which should not have been said in
public.

What is the status of this patch? Are there any impediments?

Kind regards,

Hello Tobias,

To have systemd-growfs merged to next we need to implement backward
compatibility with stretch. This can be done inside the recipe, or maybe 
even
with splitting recipes for stretch and others.
