Which of the following is true when a file system, which is neither listed in /etc/fstab nor known to system, is mounted manually?
A. systemd ignores any manual mounts which are not done using the systemctl mount command
B. The command systemctl mountsync can be used to create a mount unit based on the existing mount
C. systemd automatically generates a mount unit and monitors the mount point without changing it
D. Unless a systemd mount unit is created, systemd unmounts the file system after a short period of time
E. systemctl unmount must be used to remove the mount because system opens a file descriptor on the mount point
systemctl unmount (systemctl umount) is a unknown command
systemctl mount and systemctl mountsync are unknown commands!
Answer B? I can’t find anything about “systemctl mountsync” anywhere!
C?
C is correct, you can check the mount unit with “systemctl” or “systemctl list-units”, unmount is done via “systemctl stop “
