[install-discuss] ZFS root install on 4GB CF fails

[Kent Watsen]

Hi Lori,

Great to here its already reported and being looked at.

BTW, I couldn't find the bug when searching by either bug # or title in 
http://bugs.opensolaris.org and http://defect.opensolaris.org...is there 
another tracking system I should search?   - I'm hoping to find out when 
the fix is scheduled for...

Thanks,
Kent
