Bug Description


We can generate HyperV Image Gallery builds for Eoan images with livecd-rootfs, but not for Bionic and Disco. These images are necessary for users to install Ubuntu on their Windows machines from the HyperV Image Gallery:

To support this, three commits need to be backported from ubuntu/master to ubuntu/disco and ubuntu/bionic:

[Test Case]

These images can be built with the livecd-roottfs ubuntu/master branch by specifying the ubuntu project and the desktop-preinstalled subproject.

For example (using the ubuntu-bartender helper script in ubuntu-old-fashioned [1]):

ubuntu-old-fashioned/scripts/ubuntu-bartender/ubuntu-bartender -- --series eoan --project ubuntu --subproject desktop-preinstalled

When backported, it's expected that these images can be built for both disco and bionic with the same parameters specified:

ubuntu-old-fashioned/scripts/ubuntu-bartender/ubuntu-disco-bartender -- --project ubuntu --subproject desktop-preinstalled

ubuntu-old-fashioned/scripts/ubuntu-bartender/ubuntu-bionic-bartender -- --project ubuntu --subproject desktop-preinstalled


[Regression Potential]

The binary hook used to create the HyperV image is isolated and shouldn't affect other image builds; however, that hook depends on a symbolic link to a hook in the ubuntu-cpc project. There's a possibility of future breakage if the ubuntu-cpc project hook is modified without taking into account its use in multiple places.

To enable the use of a symbolic link, some logic was changed in the live-build configuration script. Previously, all files were copied over as-is. Now, symbolic links in hook directories are dereferenced and turned into regular files. In practice, this should only have an affect on two files, and that affect should be safe:

livecd-rootfs $ find . -type l -print | grep hooks

This may cause undesired behavior for other users of livecd-rootfs, though, that inject symbolic links into their hooks directory.
