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.
