Thanks for that. After your post I looked at the options for
yumdownloader, and it turns out it inherits options from yum, and this
is one of them. Here's what it says about that option:
--releasever=version
Pretend the current release version is the given string.
This is very useful when combined with --installroot. Note that with
the default upstream cachedir, of /var/cache/yum, using this option
will corrupt your cache (and you can use $releasever in your
cachedir configuration to stop this).
Is it necessary to have the repo files for the desired repository
installed, or does it get them off the web in a one-off manner?
Do you know if a yum clean meta would clean up the cache corruption
after doing this?
Does this mean it is possible to update a non-running system by using
releasever and installroot? e.g. update F14 from F15
yum -y update --releasever=14 --installdir=<path to F14 root>
