Use it in init. Also respect PATH in init, remove explicit "/sbin" etc
from exec. Patch by Gabriel L. Somlo <somlo@cmu.edu>

88621d7398 Svn 16007 broke the build under gcc 4.0.3. This fixes up some of the damage 
(the e2fsprogs directory is too twisty and evil to easily fix, but I plan
to rewrite it anyway so I'll just bump that up in priority a bit).

cba1b96735 Patch from Shaun Jackman to set environment variable RUNLEVEL equal to 
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...

c58dbf28e0 - remove useless variable "status" from init_main. 
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.  "

3ab3080bc2 - use config_buffer for message() 
- 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.

b3ede5abe2 More from Jan Kiszka: this is a port of the latest sysv-init SELinux patch. 
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.

2edf52643d The whole "init is sometimes pid 3" thing is silly. Init is pid 1, anything 
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.)
