[Bug] New "mount" does not recognize loop mounts
 

When called with "-a" the new mount command always mounts the loop mounts in /etc/fstab and does not check if they are already mounted. Because "mount -a" was called twice during init, any loop mounts in /etc/fstab are then mounted twice on startup.

This problem will be solved in the future because it is on util-linux'es todo list (see function mnt_table_is_fs_mounted in "util-linux/libmount/src/tab.c"). But the deprecated mount command already has this check and I was using this feature for years.

So shall we temporarily switch back to the deprecated mount command, or just write workarounds in the init scripts?

I don't see the problem, you did read mount.c didn't you?

Yes and now I find that this bug is filesystem specific. Will dig further tomorrow.
