[pve-devel] [PATCH docs] pvesm: mark ZFS level as both

[Aaron Lauterer]

ZFS can do both, and we do use both, block and file level functionality.

A change to the column width was unfortunately needed. I renumbered the
footnotes so that the first footnote starts with 1.

We probably should also check again, if we cannot get dir storage
functionility integrated in the ZFS storage module to also support ISOs,
backups, etc etc.
