The programs mount and umount(8) traditionally maintained a list Suffices to specify on the command line only the device, or only When mounting a filesystem mentioned in fstab or mtab, it Make mount fork, so that the filesystems are mounted in parallel. Proper options) to be mounted as indicated, except for those In fstab (of the proper type and/or having or not having the (usually given in a bootscript) causes all filesystems mentioned fstab path command-line option (see below for more details). TheДefault location of the fstab(5) file can be overridden with the What devices are usually mounted where, using which options. The file /etc/fstab (see fstab(5)), may contain lines describing The files /etc/fstab, /etc/mtab and /proc/mounts None is less fortunate: the error message 'none already mounted'

When mounting it, an arbitrary keyword - for example, proc - canД«e used instead of a device specification. The proc filesystem is not associated with a special device, and Symlinks in /etc/fstab has no advantage over tags. The mount(8) command internally uses udev symlinks, so the use of Tags are more readable, robust and portable. The recommended setup is to use tags (e.g. Use lsblk -o +UUID,PARTUUID to verify that the UUIDs are really Really unique, especially if you move, share or copy the device. The command blkid -p provides details about a filesystem on the specifiedДonвЂ™t forget that there is no guarantee that UUIDs and labels are LABELs and UUIDs on available block devices.
