Well, I never use a boot pool, I boot with ext4 and just do the root |
55 |
on zfs. But, I was more interested in some external media, so I am |
56 |
looking at that Linux Recovery file system to see if I can get that |
57 |
working, or if there is a way to add zfs to the sysresc cd, I might do |
58 |
that. |
