[oi-dev] [CFT] raidz/mirror support in installer

[Alexander Pyhalov]

Hello.

I have done some work on making installation on raidzN/mirror pools 
directly from text installer.

Test images are available here:
http://buildzone.oi-build.r61.net/raidz-install-isos/ (these are minimal 
images + cheksum file).

Code is available here: 
https://github.com/pyhalov/slim_source/tree/zpool_install .

Please, test it and review code.

As for testing I've checked raidz install on 3 disks + usual install on 
MBR partition alongside FreeBSD.
Note, that our installer currently doesn't detect other OSes (after 
loader change), so you had to add chainload entry manually after 
installation to be able to boot other OSes. In my case it was

echo 'chain_disk="disk0s1:"'> /boot/conf.d/chainload

I hope these changes will land in 2016.10 (or already 2016.11?) OI snapshot.
