distro: run apt-get clean after dist-upgrade, install, upgrade operations
Some vmtest scenarios install multiple large packages which consume storage
temporarily and in some cases prevent other install operations, like creating
an initramfs, from completing successfully. This change introduces an
apt-get clean command run after dist-upgrade, install or upgrade actions.
This will clear out the local repositiry of retrieved package files restoring
space back to the filesystem.
When removing duplicate UEFI bootmenu entries do not remove the
BootCurrent entry. Fix this by adding BootCurrent to the seen set
before processing the list and then skip it during iteration of the
entries.
- Add grub config option: remove_duplicate_entries bool
- Add documentation around remove_duplicate_entries grub config
- Add unittests to verify we don't remove boot current and to
check that dupe removal can be disabled.
If a system has disks without any persistent indentifier (like serial)
then udev won't create any /dev/disk/by-id symlinks. This can happen
in VMs which do not provide serial numbers by default (e.g. virtio).
If /dev/disk/by-id did not exist then os.listdir on that path would
raise a FileNotFoundException and prevented disk_to_byid_path from
returning None (or the correct path).
This is fixed by checking if the target prefix exists and if not
return an empty dict.
UEFI: Handle missing BootCurrent entry when reordering UEFI entries
Curtin typically reorders UEFI boot entries to place the currently
booted entry at the front of the list after install. In some cases a
system UEFI may not present a BootCurrent entry and curtin will not
perform any reordering leaving a node to boot from the newly
installed entry. For MAAS deployments, this causes issues as MAAS
expects to retain control over the node via PXE booting.
Curtin will attempt to reorder the boot menu when BootCurrent is
missing (or when forced via curtin config option) by placing all
network boot entries first followed by the entry curtin installed
and appending all other entries afterward. The feature,
UEFI_REORDER_FALLBACK_SUPPORT, is enabled by default. Users may
disable both reordering and fallback support.
- unittest/helpers.py: Add with_logs support for CiTestCase
- docs: document grub: reorder_uefi and grub:
reorder_uefi_force_fallback config options.
curthooks: uefi_find_grub_device_ids handle type:mount without path
When scanning a curtin storage config for efi mount entries we failed
to handle the case where an entry does not contain the 'path' key.
Curtin storage config type:mount does not require a 'path' element.
Change to using .get('path') when looking for efi mount path.
netplan's openvswitch yaml format has changed and now openvswitch
is not a top-level type but a subkey under various top-level keys.
This change will allow for top-level or subkey matching and retains
the check on renderer type (whether netplan supports that for
openvswitch or not; it's used for NetworkManager, networkd).
tools/curtainer: do not wait for snapd.seeded.service
The curtainer tool is used in CI and other places to extract a certain
curtin source from the archive and then is used to pack/unpack the
curtin code in the correct environment. We have no need or use of
snapd in this container which currently blocks for longer than
curtainer waits for the system to boot due to waiting for snaps to
download and install.
