Command grep on line 59 of /etc/rc.d/init.d/autofs
lacks redirection to /dev/null. Should read as:
if echo $map | grep -- ':' >/dev/null 2>&1 ; then
Alternatively you may use option -q in grep.
This should already be fixed in the version of autofs in Raw Hide
(ftp://ftp.redhat.com/pub/rawhide/i386/RedHat/RPMS/). If you find
that it isn't fixed if you upgrade, please reopen this bug.
