the result of the ioctl so callers can tell if we have a tty. (0 means
we have a tty, nonzero means the ioctl couldn't find size info and we
fake 80x24. Really we should fake 80x25, but oh well...)
Otherwise if you build busybox without a given applet you get the wrong error
message when you call it via a symlink to that applet.
(You also get the wrong behavior; it tries to use argv[1] as the command
name just like busybox does for _any_ unknown, and although I doubt
"echo rm -rf *" is common usage there's no upside and enough downside to
make me nervous.)
This fixes it.
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).
can never be made because useMtab is initialized to 0, and all the other
assignments of that variable assign 0 to it. Any compiler that can perform
simple constant propogation on local variables will optimize away if statements
testing against that variable, thus the call to erase_mtab() will never be
made.
When compiling for arm using gcc 3.3.3 with FEATURE_MTAB_SUPPORT disabled,
the linker complains that it can't find erase_mtab(). The arm optimizer isn't
exactly the brightest member of the family, and apparently needs to be hit over
the head with a hammer to get its' attention...
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.
- *
obvious (and less side-effect prone in strange build environments) BB_CONFIG_H.
Yeah, I know Erik ripped it out of our copy of menuconfig (which is a good
thing), but that doesn't fix people whose headers have it inherited from
linux-kernel headers or old versions of uclibc, and Erik's fix could easily
get forgotten and reverted the next time we update menuconfig anyway...
