[ Allen Abraham ]
|
||||
* Added a hook to produce a working minimal Ubuntu image using imagecraft
|

|
||||
-- Allen Abraham <allen.abraham@canonical.com> Tue, 03 Mar 2026 10:54:22 -0500
|
||||
[ Michael Hudson-Doyle ]
|
||||
* Various quality of life improvements for hacking on livecd-rootfs:
|
||||
- Add a "ubuntu-test-iso" project that builds a not very useful ISO in 2-5 minutes.
|
||||
- Add a build-livefs script that takes care of copying the auto scripts and
|
||||
invoking lb clean/config/build with the right environment.
|
||||
- Add a build-livefs-lxd script to run the above script in a lxd vm.

||||
