Hello all,
    I've been working with the Fedora 20 image from projectatomic.io for
the past few days off and on in preparation for a presentation I'm
giving on Friday and I had a few questions that popped up.
 
1) For the command 'ostree log REFSPEC', where do I find out what it
wants as a REFSPEC? 
 
ostree refs
 
 
I tried a number of combinations of the output from 'ostree admin
status' but nothing I try seems to not error.
 
Hm, that should work.  What exactly did you run?


Only ones I remember off hand were:

-bash-4.2# ostree admin status
* project-atomic-controller 6b6b1362241f1c658b54797b51c2215e32b0978f2201eeb7cd2068276adb9015.0

2) Does the latest version of the Fedora 20 projectatomic.io VM support
installing packages "on top" (for lack of a better phrasing) using yum?
Or is that still in the pipeline?
 
Still in the pipeline.
 
 
3) I'm curious about the output from findmnt, I'm seeing entries where
the source is /dev/vda3[some_stuff_in_brackets], I'm not familiar with
what that is or where it comes from and was hoping someone could provide
clarification.
 
Those are bind mounts.  There are a few of them.
 
* /sysroot points to the physical root.
* /var is a bind mount outside the deployment root to the shared /var.
* /usr is a read-only bind mount for a few reasons, but the primary one
   is to avoid admins accidentally corrupting the object store (hardlink farm)
 
I'm sure I'll come up with more questions in the future and would like
to apologize if this is line noise, but also offer some preliminary
gratitude to whom ever has answers.
 
No worries, we're still very much spinning up on the docs side.
