Adding *linux
Adding linux-safe
Adding BeOS

?

(also note using ``make dep clean bzImage modules modules_install'' is 
healthier, since it doesn't continue blithely on if there is an error in a 
previous make)

A quick grep of the lilo sources reveals no such error message.
A quick grep of the kernel sources reveals:
arch/i386/boot/compressed/misc.c:               error("ran out of input 
data\n");

ooo.

checking around here, it seems this error occurs when gunzip() calls 
get_byte() and get_byte() for some reason cannot return more input.  Perhaps 
you have a disk problem?  Perhaps you didn't run lilo?  Perhaps your kernel 
did not compile properly and you didn't notice? (watch for "image too large" 
type errors).

>Should I have done a make dep??

yes and no; changing kernel options changes conditional defines, which 
changes which files are included, which changes the dependencies.  But, if 
you've made clean, it's unlikely to cause you trouble unless you decide to 
modify source files.
