The halt.sh script copies /proc/mounts to /etc/mtab before trying to unmount, so I think that this is not the problem. Thanks anyway, Rafael pgpDiW4SjDffk.pgp Description: PGP signature

In the embedded world /etc/mtab is often a symlink to ../proc/mounts and everything works well. -- Ned Ludd [EMAIL PROTECTED] -- gentoo-dev@gentoo.org mailing list
[gentoo-dev] unmounting a filesystem mounted by /init (initramfs)
I am trying to build a system that uses a unionfs as root. The init script is based on the one used by gentoo and uses initramfs. The problem is how to remount the unionfs constituents read only during halt. cat /proc/mounts displays /dev/hda1 (ext2) mounted rw in /memory. The problem is that /memory is no longer visible after the init script did a chroot and a mount -o remount,ro /dev/hda1 says that /dev/hda1 is not mounted! does any anyone has an idea?
