Installing dracut on the install client

[Robert Markula]

Howdy,

anyone succeeded in installing dracut on a Debian stretch client using FAI?

I can switch to dracut on a conventional (non-FAI) install just fine
using these commands:

apt-get --no-install-recommends install dracut-core
cp -p /boot/vmlinuz-4.9.0-8-amd64 /boot/vmlinuz-4.9.0-8-amd64~dracut
dracut -f /boot/initrd.img-4.9.0-8-amd64~dracut
update-grub

But on a system that got installed via FAI this won't work. Tried both
booting into a system that already got installed via FAI and repeating
the above steps as well as using a quick&dirty FAI script like that:

$ROOTCMD apt-get -y --no-install-recommends install dracut-core
cp -p $target/boot/vmlinuz-4.9.0-8-amd64
$target/boot/vmlinuz-4.9.0-8-amd64~dracut
$ROOTCMD dracut -f /boot/initrd.img-4.9.0-8-amd64~dracut
$ROOTCMD update-grub

Both steps fail with a kernel panic right after GRUB if the dracut entry
is chosen.

Cheers,


Robert
