Bug description:
[Impact]
* Affects environments where the base image is read-only but kernel
modules are copied from the initramfs to the real root via cloud-
initramfs-copymods package.
* This affects users of our stable release images available from http
://cloud-images.ubuntu.com.
* The attached fixes ensure /lib/modules always exists by creating it
explicitly instead of relying on it to come from a package.
[Test Case]
* Download http://cloud-images.ubuntu.com/bionic/current/bionic-
server-cloudimg-amd64.squashfs
* Unpack it via `sudo unsquashfs bionic-server-cloudimg-
amd64.squashfs`
* Inspect the unpacked root filesystem and find that '/lib/modules'
is missing.
* Install local build scripts as described at
https://github.com/chrisglass/ubuntu-old-fashioned (note: you will
need ubuntu-old-fashioned master for cosmic)
* Re-build the images using the updated livecd-rootfs package.
* Unpack the resulting livecd.ubuntu-cpc.squashfs artifact using
unsquashfs again.
* Inspect the unpacked root filesystem and find that '/lib/modules'
exists.
* It is pure luck that package purges which are done analogously in
Cosmic image builds do not remove '/lib/modules', hence this fix is
introduced there, as well.
* Xenial is not affected.
* Test builds were carried out for Cosmic and Bionic with the expected
results.
[Regression Potential]
* This is a fix to a regression. The existence of the directory had
previously been ensured, but the mkdir call got lost in recent re-
factoring. See also:
https://bazaar.launchpad.net/~ubuntu-core-dev/livecd-rootfs/bionic-
proposed/revision/1678
https://bazaar.launchpad.net/~ubuntu-core-dev/livecd-
rootfs/trunk/revision/1681
* Packaging tools should not take offense at the existence of a
directory, even if it was not part of a package. So potential for
unforseeable regressions is very low.
===ORIGINAL BUG DESCRIPTION===
Let me first start with saying MAAS is *not* using iSCSI anymore and
is *NOT* in this case either.
For some reason now using enlistment, commissioning, and deploying the
ephemeral environment will block for 1 min 30 seconds waiting for the
iSCSI daemon to succeed, which it never does.
This increases the boot time drastically.
