executable if we asked to exec someting with argv[0] == known_applet"
Use it in init. Also respect PATH in init, remove explicit "/sbin" etc
from exec. Patch by Gabriel L. Somlo <somlo@cmu.edu>
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.
bb_xx_msg will ever try to send output to syslog.
Add "select CONFIG_FEATURE_SYSLOG" to relevant applets.
This allows to omit syslog code if we do not have
any syslog-capable applets in the build.
init's argv[1], so if you append "single" to your kernel command line and
the kernel doesn't parse it, RUNLELEL=single.
Plus a few unrelated header cleanups while I was in the area...
http://www.opengroup.org/onlinepubs/009695399/functions/waitpid.html suggests
that we need not specify a status if we don't want, and we don't.
"If wait() or waitpid() return because the status of a child process is available, these functions shall return a value equal to the process ID of the child process. In this case, if the value of the argument stat_loc is not a null pointer, information shall be stored in the location pointed to by stat_loc. "

- add second argument to waitfor(*action,pid); if action==NULL then use pid tor
wait for. If an action was given, we wait for the action to finish just as
before. In run() remove second and third occurance of the same functionality
the waitfor() call now provides.
Adjust the former only caller of waitfor accordingly.
PS: Not using waitfor but creating a second function used a few bytes more than
simply extending and reusing waitfor.

It makes busybox invoke the libselinux library function to load the binary
policy right at system start-up. It was successfully tested on a mini-SELinux
system. Note: requires recent libselinux. I'm using 1.28.
else is a kernel bug. Both 2.4 and 2.6 should get this right now. This
should fix the bug IraquiGeek is seeing (although killall still needs to
be fixed.)
The init applet will restart (re-exec) itsself when it
receives a SIGHUP. However, just before it enters its
main loop, it resets SIGHUP to either re-load the inittab
(or ignore it if no inittab is used). Thus preventing
the re-exec option from being triggerable.
This patch adds a signal handler for SIGQUIT for init that
always causes init to re-exec itsself (along with killing
anything else that might be still running).
Hello, all.
Busybox init does not handle removed inittab entry correctly.
# I'm sorry about my poor english, but you can find
# what I would like to say from patch, isn't it?
even if you apply this path,
when yoy try to change a command line option in inittab,
you have to do following steps.
1. remove old line from initrd
2. send HUP signal to init
3. kill old proces which is invoked from init.
4. append new line to inittab
5. send HUP signal to init, again
patch is against current CVS + last patch witch I send it last.
"kill -HUP 1" reloads inittab, and when I append one line to inittab
and send HUP signal two times, It will starts 2 process.
patch against current CVS is attached.
Hi!
I've created a patch to busybox' build system to allow building it in
separate tree in a manner similar to kbuild from kernel version 2.6.
That is, one runs command like
'make O=/build/some/where/for/specific/target/and/options'
and everything is built in this exact directory, provided that it exists.
I understand that applyingc such invasive changes during 'release
candidates' stage of development is at best unwise. So, i'm currently
asking for comments about this patch, starting from whether such thing
is needed at all to whether it coded properly.
'make check' should work now, and one make creates Makefile in build
directory, so one can run 'make' in build directory after that.
One possible caveat is that if we build in some directory other than
source one, the source directory should be 'distclean'ed first.

Updated patch: get rid of syslog_msg entirely. Request from Erik Andersen.
