Do we need mode=1777 for /mnt and /media ? Those are not really dirs that have the same semantic as /tmp, they are more dirs with a similar semantic as /run AIUI. Or is there soemthing I'm missing here?

Without this change, when I run stat on /mnt and /media it actually shows mode 1777 already, so I think that is the default mode. This just shows that more explicitly. So we can remove it I guess, I do not have a strong opinion either way.

Set safer options for mount points backed by tmpfs and writable by all users, so we make sure that nosuid,nodev are set. The options are the default ones recommended by systemd (see /usr/share/systemd/tmp.mount) and we were actually using them already for /tmp in the initramfs.
