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?
