May I suggest using the ``id'' program in place of ``who'' or ``whoami''
(it's already in the coreutils and could be added to the bootstrap
binaries)? The ``id'' program is far more flexible, returning numric uid,
gid, or names depending on the options. At least on Linux systems, it's
well integrated with the underlying authentication method, using
/etc/nsswitch.conf, to return the appropriate information from files, nis,
ldap, etc. as necessary.
Using ``id'' would also simplify several of the macros and methods used
during the bootstrap process that now use a combination of cat, ypcat,
grep, and awk to extract this information from the system.
whoami -> id -un
%define l_muid %(id -u %{l_musr})
%define l_mgid %(id -g %{l_musr})
%define l_mgrp %(id -gn %{l_musr})

Cutting the space budget really restores my faith in humanity. It
eliminates dreams, goals, and ideals and lets us get straight to the
business of hate, debauchery, and self-annihilation.
