Hi Christopher,

Thank you for the patch.

Yes. Otherwise, it would warrant a version bump with every update. As
you already mention, Built-Using will give the exact version.

Well, the way it has been managed so far is the maintainer and other
interested users keeping an eye on the updates to linux-source package
and request a (binary-only) rebuild of the user-mode-linux package,
which then picks up the latest linux-source packages' changes.

Ideally, I would like to see an automated way of doing this but so far
this has been done manually.

In the longer run, in the most ideal scenario, user-mode-linux should
be built as one of the targets of the linux package itself. But that
hasn't happened at all.

Thanks. I have merged it into the packaging repository. So this should
now give a nice notifier on the Debian Tracker page, when the linux-
source package is newer.

But requesting a rebuild would still be a manual step.
