Thanks for the patch!  It looks helpful.

g_option_context_set_description doesn't steal its argument, so you need
to make a local variable and call g_free().  This is easier with the
"ot_lfree" macro.

The first just initializes an ostree-as-vcs repository - like the rest
of the non-admin commands, you can run it as non-root.  This is used by
the gnome-ostree build system to put binaries into an "archive mode"
repo that could be in the building user's home directory or wherever.

"ostree admin init" sets up for a system deployment - this includes a
"bare" repository, but also prepares a directory for copying the host
kernel modules, and potentially other things in the future (e.g. sanity
check you have a supported version of GRUB).  Like the other admin
commands, it really only makes sense to run as root.
