Re: [Gluster-devel] pre6 - SEGV on first try

[Matt Paine]

Hi August - great to hear someones using the RPM's :)

I'de love to hear some feedback on your experience if you get a chance.
Any hints on how they can be improved would be fantastic too.

You can download prebuilt rpm's (built on centos-5) from the download
section now.....

Thanks.

Matt.
