Description Elmar Stellnberger 2007-04-05 09:30:17 UTC

mount --bind -r /home /mnt/home
touch /mnt/home/hug

mount
...
/home on /mnt/home type none (ro,bind)

 Mounting home ro again will be useful if we want to assert that a certain program can not change its content (f.i. to prevent data loss by misconfigured sync or to prevent data corruption if user data is accessed by an untrusted program.). Showing up the ro flag will make the user think himself safe wrongly!

persists in Opensuse 10.2.

To omit this for bind mounts in mtab would mean a whole lot of logic. We are not going to implement this. Read Only bind mounts are a feature that is coming. Until then we have to live with the wrong mtab entry
