I'm experiencing a strange behavior. After having remounted / to readonly, I'm doing a sha1sum on /dev/sda1 (which is mounted on /) Then, I reboot, GRUB starts the kernel with the ro option, when I do a hash of /dev/sda1 the sum has changed. This only happen when the rootfs hash been mounted ro, then remounted rw to make some changes and remounted ro. On the next reboot the hash will change, but only one time. Next reboots will not alter the control sum, until of course I remount it RW. Here's a small shell script that show that some changes are made between "mount -o remount,ro" and umount. On my system the might run 1 time before failing as well as 20.
