25 Thank you for your extensive feedback. :)

27 I think you've done a pretty good job of showing the complications involved in putting together
28 your own lustre kernel. It sounds gnarly. What I take away from this is the need for a vanilla
29 kernel patchset from CFS, preferably for 2.6.18 or higher. If there is already at least the
30 basis for a vanilla 2.6.18 patchset in the current beta, that could be the starting point for an
31 ebuild that would be of use for a while.

33 Its been awhile since I last tried running Lustre. Perhaps it is time I tried building a 2.6.18
34 lustre-ized kernel. It depends on how good the patchset provided by CFS is. I don't have the
35 bandwidth to go through the extensive process that you did to get a working kernel.
