command line, initialize singlemount's rc to an error value so it doesn't
think it succeeded when it didn't, use absolute path when associating a
loop device (and the previous FEATURE_CLEAN_UP logic related to that was
freeing the wrong thing), move reading of /proc/filesystems to where we can
re-read it (when it's empty) for every entry on a "mount -a" so that when
/proc is mounted as the first entry, the later filesystems can autodetect
filesystem type.
the new infrastructure is reentrant so in theory it's capable of handling
mount -a sanely. It can also re-use existing flags with remount, handle
-t auto, mount -a -t, and several smaller bugfixes.
if we don't zero it after closing it we re-close a filehandle that isn't
open, and since this is a file _pointer_ it segfaults on a double free.
Yeah, subtle bug. I need to break this out into separate functions if I can
figure out how to avoid making the code larger while doing so. Part of
the general -a and -o remount work I need to do, but that's after 1.1.0...
added to the list, and my assumption that nfsmount() actually called
mount() was incorrect (and I coded it wrong anyway; I hate having to touch
codepaths I can't personally test).
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

- * Rewrote fstab while loop and lower mount section. Can now do

Hi to all,
This patch is useful for:
1) remove an unused var from extern char *find_real_root_device_name(const char* name)
changing it to extern char *find_real_root_device_name(void).
2) fixes include/libbb.h, coreutils/df.c, util-linux/mount.c and util-linux/umount.c accordingly.
3) fixes a bug, really a false positive, in find_real_root_device_name() that happens if
in the /dev directory exists a link named root (/dev/root) that should be skipped but
is not. This affects applets like df that display wrong results
Yes, I know busybox is in feature freeze. If this two-liner is too much
that's fine, but it's handy.
This patch allows busybox mount to support "-o move" just like it
supports "-o bind", which is the equivalent of util-linux "mount --move".
Usage is:
mount -o move /mnt/point/1 /mnt/point/2
where /mnt/point/1 is an already mounted filesystem; it will be moved to
/mnt/point/2.
This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.
Erik - please apply.
Authors - please check that I didn't corrupt any meaning.
Package importers - see if any of these changes should be
passed to the upstream authors.
I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.
What is "pretect redefined for test" in cmdedit.c?
Good luck on the 1.00 release!

it will properly fall back to /proc/mounts when /etc/filesystems
is missing, allowing mount to guess the correct fs type when a
fs type is not explicitly specified.
-Erik
"rootfs" entry as well as the traditional "/dev/root" entry. This caused
applets such as mount and df to display two root filesystem entries....
This teaches the relevant utilities to ignore the "rootfs" entry.
-Erik
during 'mount -a'. If the user wants to do that, hey, its their
lifs. If the nfs server is down and they don't want to wait for
nfs to time out, that is their problem.
-Erik
1) ping cleanup (compile fix from this patch already applied).
2) traceroute call not spare ntohl() now (and reduce size);
3) Fix for functions not declared static in insmod, ash, vi and mount.
4) a more simple API cmdedit :))
5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)
1) fixed a bug that could crash df, mount, and umount applets if the root
device name was longer then the word "root" (/dev/loop1 vs /dev/root) -
2) severl functions needed static declaration in the umount applet
3) update declaration for function in last_char_is() in libbb
to multibuild.pl. I did a little formatting adjustments to make it
_very_ obvious when things stop working. I also removed the USE_PROCFS
config option -- just do the right thing when USE_DEVPS_PATCH is enabled.
-Erik
the first is a cleanup of tar --exclude
the second changes mount so mtab works more as it should, and
also allows mount to use the traditional short form (i.e.
'mount / -o remount,rw' now works.
While inside tar, I changed it to use getopt...
