It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts

Major rewrite of mount, umount, losetup. Untangled lots of code, shrunk
things down a bit, fixed a number of funky corner cases, added support for
several new features (things like mount --move, mount --bind, lazy unounts,
automatic detection of loop mounts, and so on). Probably broke several
other things, but it's fixable. (Bang on it, tell me what doesn't work for
you...)
Note: you no longer need to say "-o loop". It does that for you when
necessary.
Still need to add "user mount" support, which involves making mount suid. Not
too hard to do under the new infrastructure, just haven't done it yet...

The mount command will detect you are trying to mount a file instead

loopback device. The umount command will also free that loopback

Major rewrite of mount, umount, losetup. Untangled lots of code, shrunk
things down a bit, fixed a number of funky corner cases, added support for
several new features (things like mount --move, mount --bind, lazy unounts,
automatic detection of loop mounts, and so on). Probably broke several
other things, but it's fixable. (Bang on it, tell me what doesn't work for
you...)
Note: you no longer need to say "-o loop". It does that for you when
necessary.
Still need to add "user mount" support, which involves making mount suid. Not
too hard to do under the new infrastructure, just haven't done it yet...
The previous code had the following notes, that belong in the version
control comments:
- * 3/21/1999 Charles P. Wright <cpwright@cpwright.com>
- * searches through fstab when -a is passed
- * will try mounting stuff with all fses when passed -t auto
- *
- * 1999-04-17 Dave Cinege...Rewrote -t auto. Fixed ro mtab.
- *
- * 1999-10-07 Erik Andersen <andersen@codepoet.org>.
- * Rewrite of a lot of code. Removed mtab usage (I plan on
- * putting it back as a compile-time option some time),
- * major adjustments to option parsing, and some serious
- * dieting all around.
- *
- * 1999-11-06 mtab support is back - andersee
- *
- * 2000-01-12 Ben Collins <bcollins@debian.org>, Borrowed utils-linux's
- * mount to add loop support.
- *
- * 2000-04-30 Dave Cinege <dcinege@psychosis.com>
- * Rewrote fstab while loop and lower mount section. Can now do
- * single mounts from fstab. Can override fstab options for single
- * mount. Common mount_one call for single mounts and 'all'. Fixed
- * mtab updating and stale entries. Removed 'remount' default.

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 writeable, tends to get easily confused

About the only reason to use this is if you've removed /proc from
|
|
|
|
|
your kernel.
