Inside the plus repository there are drbd kernel modules for the
standard kernels and the plus kernels.

Inside the centosplus repos there are also xfs kernel modules for both
the standard and plus kernels.

The naming convention concerning %dist for certain files, is that
upstream is ever chancing their %dist.  In this newest incarnation, they
are going to use:

.el4 and .el5

So, centos wants to use .el4.centos and .el5.centos  (in the past, we
did use .centos or .c4 or .centos4)  the %dist should have no real
effect on anything ... or maybe I am missing the point of the question.

One thing to remember after major changes is that it takes some finite
amount of time for all external mirrors to update ... maybe the one you
were using has the standard kernel but the plus kernel (shipped some 12
hours or so later) had not made it there yet.

I am using the i686-plus kernel and drbd modules on 8 drbd clusters
without any issues that I can see.

Thanks,
Johnny Hughes
