Rob Landley	6a6798b	2005-08-10 20:35:54 +0000	[diff] [blame]	793	Historically, Unix systems kept track of the currently mounted
				794	partitions in the file "/etc/mtab". These days, the kernel exports
				795	the list of currently mounted partitions in "/proc/mounts", rendering
				796	the old mtab file obsolete. (In modern systems, /etc/mtab should be
				797	a symlink to /proc/mounts.)

Rob Landley	6a6798b	2005-08-10 20:35:54 +0000	[diff] [blame]	799	The only reason to have mount maintain an /etc/mtab file itself is if
				800	your stripped-down embedded system does not have a /proc directory.
				801	If you must use this, keep in mind it's inherently brittle (for
				802	example a mount under chroot won't update it), can't handle modern
				803	features like separate per-process filesystem namespaces, requires
				804	that your /etc directory be writeable, tends to get easily confused
Rob Landley	17507fa	2006-05-08 02:22:24 +0000	[diff] [blame]	805	by --bind or --move mounts, won't update if you rename a directory
				806	that contains a mount point, and so on. (In brief: avoid.)
				807
				808	About the only reason to use this is if you've removed /proc from
				809	your kernel.
