- select BUSYBOX_CONFIG_FEATURE_MOUNT_FAKE
- help
- Historically, Unix systems kept track of the currently mounted
- partitions in the file "/etc/mtab". These days, the kernel exports
- the list of currently mounted partitions in "/proc/mounts", rendering
- the old mtab file obsolete. (In modern systems, /etc/mtab should be
- a symlink to /proc/mounts.)
-
- The only reason to have mount maintain an /etc/mtab file itself is if
- your stripped-down embedded system does not have a /proc directory.
- If you must use this, keep in mind it's inherently brittle (for
- example a mount under chroot won't update it), can't handle modern
- features like separate per-process filesystem namespaces, requires
- that your /etc directory be writable, tends to get easily confused
- by --bind or --move mounts, won't update if you rename a directory
- that contains a mount point, and so on. (In brief: avoid.)
-
- About the only reason to use this is if you've removed /proc from
- your kernel.
