Given that we have the sources to df, I guess we should consider the question begged: Do we want to change it to DTRT for zfs filesystems? There's no Unix Law™ that says "df(1) must use the output of statfs(2) directly and can use no longer sources of information!" At the end of the day, df(1) is just a convenient status reporting tool aimed at human consumption. It could easily reach out to "zfs list" for the data it prints for zfs volumes if what's reported by statfs(2) just isn't suitable. - Jordan
