SL have been a bit faster with 6.0, but they did IIRC not do the 5.6 nor the 4.9 yet (maybe they rebuilt some packages to still be secure, but I think they didn't finish the full distribution). So, I'm quite sure it's not as bad as you think. Simon ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

nce > it actually won't do anything positive besides changing the looks. After decades in the high precision and electronics industry, I can tell you for sure that compressed air is not seen as a good choice. It blows the dust where it doesn't belong. That may not be a big problem with a cheap PC, but it's not professional at all. If you want to do it the professional way, go to an ESD protected room, take an ESD vac and an ESD brush, wear your ESD shoes and wrist strap, and clean *carefully*. Compressed air may additionally be used in certain places, but not more. Simon ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

o Linux. You're confusing me, I always thought Linux has been ported to XFS :) There were some issues with XFS and maybe there still are. But, you can not say there are no environments where it work very stable. I've started using XFS back in the RH7.2 days and I can also tell some stories, but not all of them were XFS's fault. The only real problem was the fact that RedHat didn't chose XFS as their FS of choice which meant that just a few ressources were put into the XFS code and just a few peoples actually used it. That's the only thing where ext2,3,4 was better IMHO. Simon ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
