NetworkManager.service has 'ProtectHome=read-only', which keeps NM from writing there. I presume namespacing /home in this way counts against unmounting it. This is a good security protection for everyone running NM, so I can see it being worth the tradeoff vs. being able to move or remove /home on a live system. (It also has ProtectSystem=true, which mounts /usr and /boot read-only as well.) If you wanted to change this, drop ProtectHome=false into /etc/systemd/system/NetworkMananger.service.d/override.conf (possibly by using sudo systemctl edit foo NetworkMananger). -- Matthew Miller <mattdm at fedoraproject.org> Fedora Project Leader
