-  [ Tobias Heider ]
-  * Fix ISO builds when KERNEL_FLAVOUR != generic.

-livecd-rootfs (26.04.22) resolute; urgency=medium
-
-  [ Oliver Gayot ]
-  * Pull the model from Launchpad's lp:canonical-models
-    repo, instead of having it uploaded as part of livecd-rootfs. This
-    indirection makes it possible to update the models without requiring a new
-    upload of livecd-rootfs every time.
-
-  [ Michael Hudson-Doyle ]
-  * Fix two more problems with livefs-built ISOs:
-    - Generate the for-iso squashfs in the right place for Kubuntu.
-    - Fix confusion about the kernel path on the ISO on riscv64.
-
-  [ Tobias Heider ]
-  * Fix pool generation when using extra_ppas.
