> Easy to change this. (one-liner).
I'm not so sure it's that easy. The problem I hit with using libguestfs
for this sort of stuff is that you really need to be sure the SELinux
label of critical files like /etc/passwd is set. It's hard to do that
from the outside - doing it *inside* the system on boot means we use the
Agreed... but, I do do it inside. :)
I'm not sure if this is now equivalent to the new --selinux-relabel flag
for virt-builder. If it is, we can simplify this.

think. The issue I see is more the second part - the semantics
around how we change the contents of the target system.

Definitely! Do you have some bandwidth to work on this/continue the
To be honest, not a lot, actually. If it would help, I will be in Westford
next week, and I am happy to meet if you want to hack on this, or iterate
quickly over some of the ideas.
There are a few aspects to this:
1) Content definition - what packages are installed?
2) Partition layout
3) System default configuration (vagrant user, vagrant ssh keys, sudo)
To me, Anaconda+kickstart files are the thing to use for #1 and #2. In
words we're just talking about another Fedora Cloud type image,
except with Vagrant as the "hypervisor".
For #3, kickstart files are probably also the way to go. My script was
hack because I didn't have ostree support in Anaconda, but now I
There's a general question here about anaconda versus virt-builder; when
should you "rebuild" versus "post-customize". To me the answer comes
to the package set. If for example we wanted different packages in the
Vagrant image, then it would need to be an Anaconda rebuild.
So, I must say, that I love Anaconda for it's use case, however in
general, it's the reason that virt-builder and vagrant are so useful. The
vagrant user or really most people (IMO), don't want to have to muck
around with getting every anaconda setting right... If I can build this on
top of an already built base image, then there is less chance for error.
IOW, I'm glad Anaconda exists, but I want to use it as little as possible.
What OS image can't you build with virt-builder? I don't know that it does
anything to the template that can't be properly fixed with --flags to
virt-builder... And it's easy :)
As a side note, these comments might not make much sense in light of some
of the os-tree stuff you're doing, but I'm not up to speed on all the
specifics, so my commentary assumes that stuff doesn't exist. My bad if
that's the case.
