Agree - I use that as my, well, rescue image in part because it ships |
| 12 |
recent kernels and has btrfs support. Just be sure to use the most |
| 13 |
recent version, and boot with the alternate kernel (which is currently |
| 14 |
3.18-based). With btrfs you'll want a recent kernel - I am currently |
| 15 |
tracking 3.18 which is the most recent longterm, and will probably |
| 16 |
jump to the next longterm when it matures. |

Just avoid parity raid (raid5/6) for now - that is very immature and |
| 19 |
there are constant reports of problems (it really was only supported |
| 20 |
at all in the last few months). Also, if you want to migrate an |
| 21 |
existing ext3/4 partition check the lists as there have been a bunch |
| 22 |
of threads about conversion issues recently - that should be a |
| 23 |
non-issue if you're just formatting a new partition. |

Grub2 can also read your kernel/initramfs from btrfs, so I'd recommend |
| 26 |
it even though you're trying to avoid it. Otherwise you're probably |
| 27 |
going to need a separate ext4 boot partition (I don't think legacy |
| 28 |
grub can read btrfs). I just make install my kernels and use |
| 29 |
grub2-mkconfig - it is nice having a list of older kernels |
| 30 |
auto-updated. Or you can hand-roll the config like you do in grub - |
| 31 |
it isn't any harder than it used to be but there just aren't as many |
| 32 |
docs on how to do it. |
