and I don't expect you to.

well, fsck worked.

The partition was md1 - which means /var, which also houses portage tre=
e on my=20
setup and some other vital stuff.

The first run with --build-fs failed with an 'unknown plugin id' error=20
finishing with an 'operational error'.
Secound run with --build-fs was successfull with only some files in=20
lost+found. The important stuff seems to be there.

R4 worked for me fine for a long time. But it seems like I should migra=
te the=20
more important partitions away from it. How is reisefs doing at the mom=
ent?

Gl=FCck Auf,
Volker
