Setting up a loopback also resets the block size (to 1k, it looks like). The difference is that when mounting without loop, BLKBSZSET fails with EBUSY, but with loop, I can change the block size *after* mounting. > It was discussed here: > http://lkml.org/lkml/2005/2/21/136 Yeah, that's the thread I linked previously. -- Glenn Maynard ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
