Description Need Real Name 2000-09-09 19:28:52 UTC

Unmountings of filesystems are done by /etc/rc.d/init.d/halt during
shutdown or reboot.  Some filesystems are not unmounted but remounted
read-only, e.g., the root filesystem.  Unfortunately that does not imply
that the buffers are flushed to disc.

Suggested solution:  Put a sync-command at appropriate place in
/etc/rc.d/init.d/halt.

I have never had any problem with this until I started using raid1 on the
root-filesystem so that might be crucial for this bug to actually cause
problem.

I am unable to reproduce this bug in a certain way.  However, sometimes
changes in files close to a reboot are lost.

Version:  Redhat linux 6.2, i386, initscript-5.00-1.  Other versions or
platforms have not been tested.

After hints from some friends I checked the source code of the kernel and
remount do sync the discs.  If there is a bug here, it is not in the
initscripts.

My unability to reproduce the bug makes me suspect that I have made some
mistake.  At least I don't expect someone to spend time on this until I can
produce a better bug report.  Therefore I classify this as not-a-bug.
