Are you intending to remove the name= mount option entirely, or just intend to remove that you can change it in remounts? systemd uses name=systemd to get its own private cgroup tree, that has no controller bound, hence we kinda need this option. Or are you suggesting there was an other way to get a private cgroup tree that systemd can use for grouping and labelling things? Lennart -- Lennart Poettering - Red Hat, Inc.
