And you never intend to use any programs that nlist() the kernel to local
symbols.  Like netstat, or ps or uptime.

Or worse, you hose your system and then post questions about how to
recover a hosed UNIX file system.  There's a reason that a lot of
these files are owned by root (or bin or anything else) and why normal
users don't have write permission on them.  Experiment all you want,
but you ought to be sure to make a backup first and know how to
restore from that backup.  

Is it really worth the 80k-odd bytes you get back?  This reminds me of
the common user-error: I deleted that /vmunix program that I never
use, and now my system won't boot!  I suspect that he *was* really
joking, like they guy that suggested you compress your swapfile. [No
you can't do this.]
