Then I would suggest that you reboot, then change to single user mode,
remount the filesystem read-only and start your check.
The second suggestion that I have would be to search the rc scripts and
find out where mount is called to remount the fs read/write and stuff a
bash command right before it
- how can i tell gentoo to do a real complete check of the rootfs at
startup (where the rootfs should be read-only mounted)
- how can i do that via ssh on a running system
- which paramters can i pass when booting gentoo, so that it boots into
maintainance mode where the rootfs is still mounted rea
