What the line is trying to do is run uusched as user uucp.  If you read the
man page for su, you will see that they say that su <login> -c <command> is
legal.  The program su starts the shell program for uucp (from /etc/passwd)
and hands it the "-c <command>" as an argument.  Unfortunately, the "shell"
for uucp is uucico, not the expected "regular" shell, like sh, csh, etc.
Consequently, uucico fails with the above error message.

A fix for this is a fake user, say uucp-adm, that has the uucp uid and gid,
but has a "regular" shell.
