Continued from last post,
Now /dev/sda1 being mounted as ext2 I made the rsync test:
- - - - - - - -
#!/bin/bash
UPPER_BRANCH='/mnt/rw_root/'
LOWER_BRANCH='/mnt/ro_root/'
mount -o remount,udba=notify /
mount -o remount,rw ${LOWER_BRANCH}
case $UPPER_BRANCH in
*/)
;;
*)
UPPER_BRANCH=$(echo ${UPPER_BRANCH} | sed
's/\(.*\)/\1\//') ;;
esac
rsync --exclude=".wh.*" --exclude=lost+found -vaHSx --devices
--specials ${UPPER_BRANCH} ${LOWER_BRANCH} #find . -name ".wh.*" -and
-not -name ".wh..wh.*" | sed 's/^\.\//${LOWER_BRANCH}\//' | sed
's/\/\.wh\./\//' | /usr/bin/xargs -d "\n" rm -i
sleep 1
mount -o remount,udba=reval /
mount -o remount,ro ${LOWER_BRANCH}
- - - - - - - -
Result:
- - - - - - - -

This doesn't get fixed automagically at next reboot...
...
Note, that the script doesn't delete anything from the UPPER_BRANCH!
