Requires fiddling with /etc/fstab, at least that is a file
that we never touch.  It's harder for installs that need
TRIM to be off all the time as the first boot does actually
enable it.  That means after the install is complete it needs
to be CTRL+C'ed and the fstab entry modified before reboot.

If one deletes "plugins.inc", this way the plugin system can be
disabled.  That's a lot better than removing plugins.inc.d/
content and executing the stubs everytime anyway.

for example, return all active non virtual interfaces:

$interfaces = legacy_config_get_interfaces(array("virtual" => false, "enable" => true));

(cherry picked from commit 2fd3a68d)

While this is a neat milestone, it becomes apparent how convuluted
the code path and interface info polling is.  Looking at it, the
whole interface layer can probably make performance jumps to at least
twice the read or reconfigure speed...
