If these patches solved all the problems and made things work wonderfully I'd probably say we'd take them. Unfortunately I don't consider taking 1.5 hours to build am 8GB filesystem "wonderful", its rather worrying and I don't think its performing any where need fast enough for our needs :(. Patching genext2fs at this point in the cycle is a rather risky undertaking too and I'm getting very concerned about this. We might have to look at alternative ways to solve this problem. I think Darren said he might help look at this and has some other ideas. Darren? Cheers, Richard
