Bug 5083

/etc/rc.d/rc.sysinit seems buggy:

1) The if/else clauses for raid startup are wrong, they
always fails.
2) the line "grep 'raiddev' /etc/raidtab ..."
line ignores commented out lines.
(e.g "# sample raiddev" is accepted)

This change fixes the startup problem:

# Add raid devices
if [ -f /proc/mdstat -a -f /etc/raidtab ]; then
        echo -n "Starting up RAID devices: "

        rc=0

        for i in `grep "raiddev" /etc/raidtab | awk '{print
$2}'`
        do
                RAIDDEV=`basename $i`
                RAIDSTAT=`grep "^$RAIDDEV : active"
/proc/mdstat`
                if [ -z "$RAIDSTAT" ]; then
                        # Try raidstart first...if that
fails then
                        # fall back to raidadd, raidrun.  If
that
                        # also fails, then we drop to a
shell
