How about a crc-32 of either the kernel or the System.map file stamped
into both? Actually, a 32 bit random is probably good enough....

You could even put most of the work in user space - read a /proc/kernelid or
/proc/mapid that just reports the number, then user space (rc files?)
looks thru the (locally defined) list of possible locations, and writes
it to /proc/locations/System.map

Yah, it'll miss once in a *very* great while, but not often! Besides,
this way they stay separate files that won't bloat loaded image or
disk/diskette size. Of course, if you can't find those files, you're
in the same shape we are today....

I think the kernelid is a better choice, because you can stamp .config
files & other stuff the same way, w/ the same number.

later!
