Going with this & making an addition.
I usually add this to my periodic.conf:
daily_status_disks_df_flags="-h -i -t ufs,zfs"
Adding '-c' for a system that has ZFS produces results that are not
correct for a total, but stating it more for reference. It might make
sense to patch df(1) so it looks at the begging portion of the
file-system up to the first '/' and get the value for free and used from
that but this is tricky when refreserved, quota and other properties
come into play and is a little beyond what df is meant for. But that
subject is for another thread.
I do wonder if it would make sense to just split the daily_status_disks*
into daily_status_{FILESYSTEM} to look like this
daily_status_ufs_df_flags etc... and keep daily_status_disks_df to be
defined as daily_status_disks_df="ufs zfs xfs"
Ignore random babbling meant to spur thought. ;)
