The man page is rather sparse, for example no description of the SCM_*
macros recognised by mock.  In any case I did look at site-defaults.cfg,
for testing I decided to provide everything on the command line and the
following is what I came up with.


$ mock --buildsrpm --scm-enable \
       --scm-option spec=/path/to/outoftree/SCM_PKG.spec \
       --scm-option method=git \
       --scm-option package=notmuch \
       --scm-option git_get='git clone SCM_BRN /localpath/SCM_PKG SCM_PKG' \
       --scm-option branch=master \
       --scm-option write_tar=True -v


And I get an error message like this:

[...]

DEBUG: Preparing SCM sources
ERROR: Can't find spec file
/tmp/tmpHd0D2H.mock-scm.notmuch/notmuch//path/to/outoftree/notmuch.spec
DEBUG: Clean SCM checkout directory
DEBUG: remove tree: /tmp/tmpHd0D2H.mock-scm.notmuch


Now instead if I put the relative path of the buggy spec file in the
repository like this:

  --scm-option spec=relative/path/to/intree/SCM_PKG.spec

then the srpm build is finished correctly.

What this tells me, mock can either get everything from scm, or
everything locally but there is no way of using an out-of-tree spec file
with a snapshot from an scm.  Do you think there can be any other
possibilities?  If not, would this be a valid feature request?

Thanks for your opinion.
