[BusyBox] question about init and login

[Chien-Yu Chen]

Hi!

  here are 2 questions that's bothering me..

1.  Where is the code for linuxrc?  I suppose linuxrc shared the code
with initrc, but can't seem to find linuxrc....would like to remount /
from linuxrc with a different ramdisk size than the initrd

2.  when I log in, I am getting " u not an object" and " un not an object"
  Is "u" and "un" short for something that I turned off?  can't find
those 2 commands..

thanks for any pointer
