Subject: feat(debian.conf): default to initrd.img-${kernel} on Debian/Ubuntu
Extend the Debian/Ubuntu Dracut configuration to change the default
`initrdname` to `initrd.img-${kernel}`. This is done to keep the name
the same as initramfs-tools which has been the default for a long time.
This change will be carried for quite some time to ease the switch from
initramfs-tools to dracut.
