I keep a few old kernel binaries around that I know have worked.
They are not ancient; the oldest is 2.6.19*
Am I correct in believing that I can run these backup kernels even if
I discard the corresponding sources. I am fairly sure that I need
keep only the contents of /lib/modules/<version> and can discard
/usr/src/linux-version, but would appreciate confirmation.
thanks,
allan

You are correct; no sources needed.

You just won't be able to build modules against them, for example. I've
run lots of kernels (on gentoo) after having deleted the source tree.
All other distributions I've ever run had the source in a completely
separate package.

yes.
and to speed up unmerging, delete the src directories first, unmerge after
that.

Thank you all for the confirmation and the suggestion to first delete
the src directory itself (to speed up the unmerge).
