boot issues

[Randy Bush]

[ this happened a month ago and i backed off ]

i386, 7.2-stable from last summer

cvsupped releng_7
made and installed kernel
buildworld
boot -s
installworld
mergemaster
reboot

hung after beastie, just as it did the other month

booted -s
mount -2 /
/etc/rc.d/hostid start
/etc/rc.d/zfs start
looked around and all seemed ok
^D
came up ok

and that is how it is running now

but why will it boot through -s and not from beastie?
