The MiniVend server should not be run as root. It should run
as a the user name you configured in when you set up the catalogs.

The name we think should run it is: $name

If you are starting the server from /etc/rc.local or another
startup file, you can use this:

su -f -c $VendBin/start $name

or if that fails:

	su $name <<EOF
$Global::VendBin/start
EOF

=head1 NAME

restart -- call bin/minivend C<->r with possible su

=head1 VERSION

1.0

=head1 SYNOPSIS

	restart [-f]

=head1 DESCRIPTION

The C<restart> script just tries to execute C<minivend> C<-r> with the proper permissions. If
the user is "root", a prompt will be made to see if you want to start as the guessed
user ID. (This is the contents of the $Global::VendRoot/_uid file.)

=head1 OPTIONS

The C<-f> flag prevents the prompt for superuser and forces quiet mode; this is how you might call MiniVend from 
a system startup script.
