Bind (hardlink) one directory to many places

ext4hardlinkmount

I need to "bind" one directory to many chrooted places. I know that I can do "mount -o bind", but this requires special processing on startup each time (run the mount).

Is there a way to do it on the filesystem directly? My fs is ext4 and it seems not to support hardlinks to directories. Hardlinking all files inside is not an option too.

Is thee a way to enable hardlinks to directories in ext4? Or any other options are avilable?

Just add lines to your /etc/fstab:

/path/to/source /path/to/bind/mount/point none defaults,bind 0 0

After doing this, the the bind mount will be performed each time the system boots.

Type this into bash:

egrep -v '^#' /etc/fstab | while read dev dir type opts dump pass ; do
    echo "mount -o remount,${opts} ${dir}";
done

On my system, this produces output like this:

mount -o remount,nodev,noexec,nosuid /proc
mount -o remount,relatime,errors=remount-ro /
mount -o remount,defaults /misc

Try it on your system. If you like it output it produces, use it, or just remove the echo and the double quotation marks from the command above.
