Found the root issue here I believe in /etc/rc.sysinit
if [ "${RHGB_STARTED}" != "0" -a -w /etc/rhgb/temp/rhgb-console ]; then
fsck -T -t noopts=_netdev -A $fsckoptions >
/etc/rhgb/temp/rhgb-console
else
fsck -T -t noopts=_netdev -A $fsckoptions
fi
It scans all file systems by default unless the _netdev option
is set, whereas in CentOS 4.x it ONLY scans the root file system
if [ "${RHGB_STARTED}" != "0" -a -w /etc/rhgb/temp/rhgb-console ]; then
fsck -T -a $rootdev $fsckoptions > /etc/rhgb/temp/rhgb-console
else
initlog -c "fsck -T -a $rootdev $fsckoptions"
fi
I'll think about filing a bug/feature request I think the 'noauto'
option should be included in the exclusion list.
Perhaps fsck should be fixed as well, according to the manpage
'noauto' means it won't get mounted when you do mount -a, perhaps
it should not get fsck'd either if you do fsck -A
