This is apparently still required; without it snapd gives an error
message like:
stateengine.go:102: state ensure error: devicemgr: cannot proceed without seeding "core"
(cherry picked from commit 7f07cc8991)
There can only be one model assertion, so we don't need to disambiguate them.
This also brings us in line with the behaviour of `snap prepare-image`, and
consistency is nice.
This also splits up the preparation in to two functions, so that images that
want to use a custom model assertion but don't have any snaps to preinstall
don't end up with the core snap installed.
When no channel is given for a pre-seeded snap, the channel
should be stable/ubuntu-XX.YY to match Ubuntu policy.
This patch adds the LB_DISTRIBUTION var to config/{binary,chroot}
to have a common way of determining the Ubuntu XX.YY version
number between hooks and auto/build.
* Only shell out to set $account when we need to use it.
* Reduce scope of $account to make it local to the function
* Fix indenting within an 'if' block
instead of having bogus root=stuff arg generated in grub.cfg, it is
actually empty. Therefore update the sed command to make the arg in
the root= token optional. This should resolve non-booting livecd cpc
images.
unmount them, instead of working from a hard-coded list. This makes
the code resilient against other submounts being added later, including
downstream.
* Also nuke the sleep / udevadm settle calls in the process, which should
never be required and slow down the builds.
* live-build/ubuntu-cpc/functions: Add a function, teardown_mountpoint,
to reverse the work done in setup_mountpoint. Lack of this function
has forced users of setup_mountpoint to implement this separately
and the implementations have diverged. (LP: #1716992)
* live-build/ubuntu-cpc/functions: Remove umount_settle function.
The was only used where teardown_mountpoint was lacking.
we don't have to leave empty space in our derivative images for packages
that have been downloaded/installed/removed. This normally isn't
relevant for the installed system, since the root filesystem will
auto-expand in place on the target disk, but lets us ship smaller
images.
* live-build/functions: also call 'apt-get update' after mounting the
blank /var/lib/apt.
