Resurrecting this thread . . .

Having had internal discussions (mainly Phil & I, by telephone) and
gradual, incremental refinements to the ELRepo kmod build process for
EL5 (as a result of establishing a similar process for EL6), I would
like to draw your attention to the e1000e kmod package that I have
just updated (to version 1.2.8) today.

The src.rpm file [1] is an example of building against the oldest
kernel (5.0, -8.el5, in this case) and provides packages that are kABI
compatible with the entire range of released kernels (5.0 to 5.5,
-8.el5 to -194.8.1.el5).

Of course both the kmodspec-el5 [2] and kmodtool-el5 [3] template
files also provide generic examples.
