Description Christian Hechelmann 1999-12-08 14:50:50 UTC
The /etc/rc.d/init.d/halt fails to stop any md? devices, because of
unmounting /proc too early.

Furthermore only ext2 partitions are remounted ro during the last phase
of the shutdown, leaving any other filesystems mounted rw.

Patch follows:

Comment 1 Bill Nottingham 1999-12-08 16:29:59 UTC
Um, anthying else should already have been unmounted earlier.

The /proc unmounted has moved in CVS; will be fixed in
initscripts-4.72 when it is released.

Comment 2 Christian Hechelmann 1999-12-08 19:48:59 UTC
Sure, but if we are trying to remount the remaining fs' ro, we'd try this for
all the fs and not only ext2.

And if it happens, that a fs cannot be unmounted (in use), it might be possible
to remount it ro, so we can get around a (possibly lengthy) fsck run on
