Comment 20 for bug 204133

Colin,

Thanks a lot, the above is invaluable. Changes to mount options in initramfs and sysctl settings should be doable. I am a bit more concerned about the last comment...

The loopback filesystem (file containing ext3) contains /, so that is never really unmounted, only remounted r/o in /etc/init.d/umountroot. As for /host (ntfs filesystem containing the root loop file) that is not even set r/o. A patch to remount /host r/o is in #186114, but was not applied since Szaka mentioned that remounting an ntfs r/o can lead to data loss (#186117). Do you think that we should proceed and have /host r/o? Would that be sufficient?

Hints welcome!
