I don't think Linux considers this a bug, it's just part of the design of the 2.4 kernels, even though it means that dump is pretty much deprecated for a mounted file system. I asked the ext2 dump maintainer about this, and he says this is "normal" and a "known design problem and not a fixable bug." Anyway, it works fine in Freebsd, so I'm good. --Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
