The kernel team has decided, together with the dracut maintainers, to
switch the default initramfs builder to dracut during the forky
release cycle, and ideally quite soon.
This means that:
Depends: initramfs-tools | linux-initramfs-tool
will be replaced by:
Depends: dracut | initramfs-tools | linux-initramfs-tool
(with appropriate minimum versions). There is no plan to force a
switch to dracut during an upgrade, but new installations with d-i
should include dracut.
It appears that flash-kernel and possibly other packages will need to
be updated to support dracut. Those bugs will be added as blockers
for this one.
