du(1) uses DEV_BSIZE, but it looks like that's the version from sys/param.h, which is always 512. I would suggest fixing that to look at the filesystem's definition, but then I'd have to figure out what the correct behaviour would be when recursing into through multiple filesystems with different blocksizes. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
