Over a year ago, Redhat promised me that with RedHat 4 (more specifically starting with the 2.6 kernels), XFS would be a standard part of their distribution and fully supported. When that didn't happen and they actually deleted what support was already there, I asked them what happened. Their excuse was they didn't have enough people to support XFS. What extra support is needed? They seemed to have worked much harder and caused themselves a lot more support problems deleting it than they would have just leaving it in there. Seems more like jealousy or `not invented here' attitude than any good logical reasons to me. XFS was developed by SGI. Redhat seems to see SGI as a competitor, so do not help your competition no matter how stupid the decision is or how much extra work it costs you. Just one of many stupid decisions by Redhat.
