[lustre-discuss] KMOD vs DKMS

[Rick Wagner]

Hi Brian,

I consider build processes somewhat fragile, especially when you expect to get the same results across a large number of hosts, like a set of Lustre servers. As a result, I favor building a single set of RPMs, testing them, and then pushing an update to the production servers. So count me in the kmod camp.

In the case of a small number of NFS servers, I might go with dkms for convenience.
