[pve-devel] [PATCH installer 0/3] fix #6285: always set up zfs modprobe configuration

[Christoph Heiss]

Fixes #6285 [0].

This also came up quite a few times already in the forum, most recently
[1] (german).

Since we do expose the option in the UI for all products nowadays (on
ZFS-on-root installations only tho), just always write to
/etc/modprobe.d/zfs.conf.

Testing
=======

Tested for each product PVE, PBS, PMG the following
  - install on ZFS, not touching the ARC size setting
  - install on ZFS, set some explicit value for ARC size
  - installing on non-ZFS such as ext4

.. and checking afterwards that /etc/modprobe.d/zfs.conf was written and
contained respectively
  - the default value for the product
  - the set value
  - again the default value for the product

Also tested each case with the auto-installer for PVE and PMG.

Diffstat
========

  run env: always return proper value for default zfs max arc size
