[BusyBox] SIGHUP re-exec broken

[Russ Dill]

I just noticed this:

Patch from  Andrew Flegg:

    Here's a pretty crude patch to reload /etc/inittab when init receives a
    SIGHUP. The mailing list archives weren't entirely clear on whether or
    not it should already happen, but didn't appear to be.

    The patch:
       * Adds a new function, reload_signal() which just calls
	 parse_inittab() and run_actions(RESPAWN)

       * Before entering the while (1) loop set up SIGHUP to call
	 reload_signal()

       * Modify new_init_action to skip the action if the same command
	 already exists on the same terminal

    This last bit means that changing already running entries is a bit
    hairy as you can end up with, for example, two shells running on the
    same virtual console. However, for solely adding/removing entries this patch
    seems to work quite well.

which was committed July 22nd, 2003. It breaks:

Add in a new restart init target, triggered by SIGHUP.  Patch from
Russ Dill, with adjustments by me.

applied December 17th 2001. Given that the latter is far more useful
(allowing one to unmount the rootfs so that it can be reflashed) and was
applied a lot longer ago. I'm thinking the reload inittab one should be
reversed.
