I mean $c{Images}.  You could provide a script (mg-download-fedora) to
download/update them.

Indeed.  The debian-installer stuff goes in /tftpboot but is handled
much the way I'm suggesting.

Right.

No, it's because in the future I want to be able to run multiple test
jobs on a single host, so the pathnames oughtn't to be fixed.  And
there is no good reason for using /tmp here.  /tmp has a number of
problems (many of which don't apply here, admittedly) so it's not a
good habit to use it.

We're talking about paths on the test host dom0 here, right ?

Thanks,
