Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]804 Enabling this feature allows automatic mounting of files (containing
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]805 filesystem images) via the linux kernel's loopback devices.
806 The mount command will detect you are trying to mount a file instead
807 of a block device, and transparently associate the file with a
808 loopback device. The umount command will also free that loopback
809 device.

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]811 You can still use the 'losetup' utility (to manually associate files

814 (If you don't want umount to free the loop device, use "umount -D".)

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]822 Historically, Unix systems kept track of the currently mounted
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]823 partitions in the file "/etc/mtab". These days, the kernel exports
Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]824 the list of currently mounted partitions in "/proc/mounts", rendering
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]825 the old mtab file obsolete. (In modern systems, /etc/mtab should be
Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]826 a symlink to /proc/mounts.)

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]828 The only reason to have mount maintain an /etc/mtab file itself is if
829 your stripped-down embedded system does not have a /proc directory.
830 If you must use this, keep in mind it's inherently brittle (for
831 example a mount under chroot won't update it), can't handle modern
832 features like separate per-process filesystem namespaces, requires
833 that your /etc directory be writeable, tends to get easily confused
Rob Landley17507fa2006-05-08 02:22:24 +0000[diff] [blame]834 by --bind or --move mounts, won't update if you rename a directory
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]835 that contains a mount point, and so on. (In brief: avoid.)
Rob Landley17507fa2006-05-08 02:22:24 +0000[diff] [blame]836
837 About the only reason to use this is if you've removed /proc from
838 your kernel.
