That's just not true, at least not for traditional UUCP -- I must admit
I've not examine the details of Taylor UUCP interactions, but I'm
hoping they are still compatible....  No UUCP-based mail system that I
ever encountered used a fully qualified path for rmail.  I'm not even
sure it would be permitted.

In HDB-UUCP it's possible specify the explicit location of binaries for
given job commands with the Permissions file COMMANDS entry.  Other
versions of UUCP have a compiled in path indicating where job commands
are searched for.

Regardless, since the source for the UUCP shipped with NetBSD is part of
the tree, it should be a simple matter of "fixing" uuxqt to search in
/usr/libexec and the /bin/rmail symlink will not be required in the
first place.
