I remember that extN uses -O and that was my first choice without much thinking. While writing the changelog "all other mkfs use -O" I did not find this correct when looking to xfs and ocfs2 manpages. > xfsprogs doesn't really have a feature flag option per se; there are just block, > inode, size, log, data etc. options which may trigger some feature set. Yeah, and this separation makes sense, as there are several options how to tune the specific area. My point is to turn on/off a whole filesystem feature via a single option that cannot be enabled by a mount option or may make the filesystem unmountable on older kernels due to incompat bits. > e2fsprogs has the rather -O feature -E extended-options set, and darned if I could > tell you the difference ;) > > but I think -O is the right option, unless you found other common mkfs's that > use something different. When in doubt, e2fsprogs conventions probably win. :) Nothing so far, tried jfs, f2fs, hfs, reiserfs.
