Hey Dag,
Thank you for taking an interest in ocfs2. You've always been a
great resource for folks working on el-like distributions and their
limited package archives. I have a couple of questions, if you don't
mind.
First, do you have any provisions in your package dependencies
to limit packages to certain update releases? What I mean is, can one
package be installed and used against EL5GA, EL5U1, ..., EL5U5? Or do
you have some mechanism to isolate a package to only a particular update
release? I bring this up because there are often ABI changes that are
not detectable via modversions or any other automatic method we
currently have.
A specific example is ocfs2 1.4, which will crash on EL5GA or
EL5U1. They do not contain mainline commit
349457ccf2592c14bdf13b6706170ae2e94931b1 "Allow file systems to manually
d_move() inside of ->rename()", which ocfs2 1.4 requires. This was
introduced in EL5U2. No function signature is changed, so modversions
will not catch the difference.
On another note, I was wondering if you have any language
mentioning that these are not the officially supported packages? I want
to be clear here. We develop ocfs2 to be used as widely as possible,
and we will never shortchange mainline or a packager like yourself when
it comes to help on ocfs2-users and other community forums. ocfs2 is
something we're very proud of, and we back that to the best of our
ability. I'm just want to have a clear story for our customers.
Thanks again,
Joel
