[Initng-svn] r3691 - initng/trunk/src

[svn at initng.thinktux.net]

Author: jimmy

New Revision: 3691

Modified:
   initng/trunk/src/initng_main.c
Log:
Now if compiled with #debug a segfault makes initng launch manually a getty on tty9 to login to and run gdb from, this is good if initng
segfaults before a terminal is launched, or after all is terminated.
