Hi Larry,

I'm not sure where the ? came from, but I think that's just the email, 
here is init:

ls -l /etc/init|od -c
0000000  -  r  w  x  r  w  x  r  -  -        1     r  o
0000020  o  t                 2  0  5  4     M  a  y
0000040  1  3     2  3  :  5  0     /  e  t  c  /  i  n
0000060  i  t \n \0
0000063

ls -l /etc/init|od
0000000 071055 074167 073562 071170 026455 020040 020061 067562
0000020 072157 020040 020040 031040 032460 020064 060515 020171
0000040 031461 031040 035063 030065 027440 072145 027543 067151
0000060 072151 000012
0000063

As for how big they are, that's just the beauty of v6, everything is 
super small. Linux is blubbery in comparison.

Will
