OK good to know. This reinforces my thinking. Is it sane for ARMv7 to have its 
own fs default? Or should all of the archs for a product compromise?

Each deliverable must have its default partitioning tested. If there are 3x 
deliverables, that's 3x default partition testing. I don't see that it matters 
if each deliverable had a different default fs/layout, because that's still 
just one default for that one deliverable. It's not multiplicative. Whereas 
before with four Partition Scheme options, 3x deliverables means 12x paths. 
It's a lot more testing to have options. One default fs/layout is a passthrough 
for each of the deliverables regardless of what it is, testing wise, but maybe 
this is untenable for anaconda or for composes?

OK. Does the anaconda default bind you into making this change in 
appliance-creator? Or is it a preference? And if it's a preference is it really 
making things easier to be all on the same thing, even though all offerings 
would have to be tested in any case?

That 22TB file system isn't running on a 32-bit kernel though.

I'm fine with XFS on x86_64, as it's very well tested there. And i686 doesn't 
bother me much as it sounds like it gets good upstream testing. I'm a little 
more concerned about it on 32-bit ARM though just because of the unknowns.
