Sorry to follow up to myself, I just wanted to note that syslog and
getopt don't seem to add much to the size of the executable:
wpeters@salty> size nologin
text data bss dec hex filename
1845 260 36 2141 85d nologin
wpeters@salty> ls -l nologin
-rwxr-xr-x 1 root wheel 5430 Nov 17 13:03 nologin*
wpeters@salty> sudo strip nologin
wpeters@salty> ls -l nologin
-rwxr-xr-x 1 root wheel 3796 Nov 17 13:05 nologin*
wpeters@salty> ldd nologin
nologin:
libc.so.5 => /usr/lib/libc.so.5 (0x2806b000)
So this may be worth the bikeshed^W^Wconsidering after the thaw.
Certainly not important enough to slushie.
