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 at salty> size nologin
   text    data     bss     dec     hex filename
   1845     260      36    2141     85d nologin
wpeters at salty> ls -l nologin
-rwxr-xr-x  1 root  wheel  5430 Nov 17 13:03 nologin*
wpeters at salty> sudo strip nologin
wpeters at salty> ls -l nologin
-rwxr-xr-x  1 root  wheel  3796 Nov 17 13:05 nologin*
wpeters at 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.
