the common workaround that e.g. other distributions do is to do this in
initramfs. probably debian should do that for all filesystems in future too.

current remaining problem in sid.

*iff* sysvinit is used.

the current package works fine on systems with systemd (not yet fixed
points 3 and 4 from above are not breaking it).
