I don't see how this buys us much, unless your ext2fs code works so differently from FFS that in-situ filesystem checks yield anything but bogus "corruption" errors that are really just the result of reading filesystem operations in mid-progress. Do you have a flag that locks the filesystem out for write access while you're checking it (and syncs it first, of course)? > Please, no ``BSD vs Linux'' or ``UFS vs Ext2fs'' war! :-) Naw, I'm more inclined to ask about Ext2FS on FreeBSD. How is that little project coming? :-) Jordan
