Installed binaries should already be stripped if they're part of the
base system. You have to make a special effort setting things in
/etc/make.conf to prevent binaries being stripped on installation.
The reason that rcp is so large on 4.x is that it's statically linked:
% ls -la /bin/rcp
-r-sr-xr-x 1 root wheel 251572 Feb 7 12:43 /bin/rcp*
% file /bin/rcp
/bin/rcp: setuid ELF 32-bit LSB executable, Intel 80386, version 1 (Fre=
eBSD), for FreeBSD 4.9, statically linked, stripped
On recent 5.x, rcp will be linked against the shared libc and
consequently rather smaller in size.
Cheers,
Matthew
