Subject: rc.d: Add a vfs_accounting script
X-Git-Tag: v3.0.0~73
X-Git-Url: https://gitweb.dragonflybsd.org/~tuxillo/dragonfly.git/commitdiff_plain/9be2bba083772211049aa695fd8e9dedd239e0e4

rc.d: Add a vfs_accounting script

* Its only function for now is to synchronize counters with the real
  disk usage of a list of mount points

* Small rc.conf example:
  vfs_accounting_enable="YES"
  vfs_accounting_sync="/home /mnt/data"
