Well, there is no choice anyway. We do have fc4 and f10 infractructure
ports. I think it's wise to use apropriate base ports. I don't think
there is any difference between f9 and f10 linux base ports.

If someone shows a difference (i.e. possibility to use f9 but not
f10 linux base port under 7.x I may change my mind).

We discussed those checks with the maintainer and his checks were good
(for his software). I can't say more than that, sorry.
