Public bug reported:
Passing mount options (here: "hidepid=2") for /proc via /etc/fstab does
not seem to work:
$ grep /proc /etc/fstab /etc/mtab /proc/mounts
/etc/fstab:proc /proc proc nodev,noexec,nosuid,hidepid=2 0 0
/etc/mtab:proc /proc proc rw,noexec,nosuid,nodev 0 0
/proc/mounts:proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0
Also, /etc/mtab and /proc/mounts are out of sync - are there plans to
link /etc/mtab against /proc/mounts? (Note: I'm not particularly in
favor of bug 906293, propsing yet another file to the mix).
The system is a fully patched Ubuntu 12.04.1 LTS (i686) in an Amazon EC2
virtual machine.
Workaround: add the following line to /etc/rc.local:
mount -o remount,hidepid=2 /proc
