Anyway, even if gstat should work perfectly for acd, I think it is no reason to have iostat/systat incomplete. Also, a reference to gstat(8) in iostat(8) and systat(1) would be nice too. Btw, is it a bug or a feature that gstat requires root privileges ? - iostat/systat can be run as a regualr user: gstat: geom_stats_open(): Permission denied -- Andriy Gapon
