Bug#765750: initramfs-tools: should probably recreate initrd after installing

[Santiago Vila <sanvila@unex.es>]

Package: initramfs-tools
Version: 0.116

When I install dracut, a new initrd is generated automatically using dracut.

If I install initramfs-tools again, dracut is removed but this time a
new initrd (generated by initramfs-tools) is not generated.

I see a lot of danger here.

Either initrds are generated automatically or they are not.

If they are, installing dracut and then reinstalling initramfs-tools
should leave the system in the same state as before.

This is particularly important because initrds generated by dracut are
not always suitable for everybody so the user might reasonably expect
that reinstalling initramfs-tools should create a "safe" initrd again.

Not sure avout the severity of this bug, but it seems that more and
more people are using dracut, so this might eventually become a real
serious problem and will bite us.

Thanks.
