Hi Mark and people.
Freedom of choice! :) I have nothing against ZFS, I myself have been
using default choices by Redhat/CentOS in the various distributions at
home and at work meaning ext3 and ext4 with LVM. So maybe some easy wiki
guidelines on how to easy switch between the technologies and pro's and
con's like the ones you and Gordan mention.
Like, I would love to see /var/run moved moved to a tempfs like
Raspberry suggests if you run on a SD/MicroSD.
BR,
Bjarne

I am also a huge fan of ZFS. I've been using it at home on my home
server's 10TB partition for a few years now (back when that was a bit
more impressive ;) ), and I even use it on some servers at work (big
fan of the deduplication feature for our backup server--BackupPC + ZFS
Dedup == Awesome).
So that said, I'm highly in favor of the OPTION of ZFS on RedSleeve.
As you've mentioned, there are some cons to it, especially to embedded
devices with limited resources. I think these types of devices should
have the ability to stay on ext.
Plus, there's some other considerations. In my case, I am currently
using the RedSleeve OS as a base for a product I hope one day to
market. I chose RedSleeve because of the stability inherent in the
upstream's derivatives, including CentOS, and last I checked, RSEL is
one of a kind--there's just no other EL-based ARM OSes out there
(which surprises me). So stability is very important for me.
Performance too (of which every little bit counts on an embedded
device). But another one that I think people often forget, is that
license-wise, ZFS is not technically compatible with linux. There are
many who choose to ignore it (myself included on my home server), but
the fact is, if I want to bring this to a commercial product
eventually, I'm going to have to pay attention to those licenses.
Others in my boat will too.
Perhaps a compromise--what if two images were kept? One that's more
"vanilla", and another with ZFS? My guess is that it's a little extra
work, but that it wouldn't be that much--you would just create the
vanilla as usual, and branch it off to modify it with ZFS.
