PC-BSD, take 2

I have been feeling restless and somehow unsatisfied lately, kinda missing some thrill in my Linux adventures. Also, some part of it is my disappointment that Debian chose the future of systemd. Means that there will not be next stable Debian install for me. All in all - I decided to start with some slightly radical projects, one of which is new visit to BSD-land.
See the previous one here.

I dowloaded PC-BSD DVD-USB-version of iso, dd-d it to usb-stick:
dd if=PCBSD10.0-RELEASE-x64-DVD-USB-latest.iso of=/dev/sdd bs=1M
and booted it without problems. With my new and better box it didn't take very long for language-menu to appear. Whole installation looks roughly identical to ver 9.2.
Only filesystem available is zfs.
The new installing option is 'grub-slice' for planting grub2 to bsd root. What a joy - at last an option to escape fucked-up MBR, and get grub-generated correct boot-code!
... Well, it wasn't. Joy, I mean.
What I got was grub 'exiterror', indicating something like 'I can't understand so many partitions or labels or whatever'. And installation ended with 'Failed'.
I found quite a lot of the same when googling about it. What I didn't find was the solution.

I mused a bit over it - mind, quite relaxedly this time - as my expectations of successful installation wasn't especially high anyway.
Conclusion:
1. I really do not need zfs for my desktop. It's an overkill.
2. There seems to be quite a lot of difficulties to get zfs pool mounted in Linux - as BSD version of system tends to be newer than Linux-provided zfs-fuse. Means, one has to do various tricks for that, or - to get some common r/w partition for those op-systems (and no, freebsd does not recognize ext4).
3. And - I am not going to repair my MBR because some silly shit wants to overwrite it. One thing I expect from op-system is that it installs as I want it to be installed. PC-BSD still doesn't do it for me.
Formatted this special primary partition I had kept for BSD to ext4, and I might try Gentoo there ...

Because my previous BSD-post had a little part about Ghostbsd, then - I took a look. As is seen there, ver 4 alpha is out (and is based on Freebsd 10). Consequently - no install-attempts just now. But I will try when 4 gets released.
