Description:
In open-iscsi 2.1.9-1 the location of the "database" (as they call it) has moved from /etc/iscsi/ to /var/lib/iscsi/. I.e.
/etc/iscsi/nodes/ and /etc/iscsi/send_targets/ are now /var/lib/iscsi/nodes/ and /var/lib/iscsi/send_targets/.

As I understand, it's because the package was changed to build using meson and coincidentally upstream merged https://github.com/open-iscsi/open-iscsi/pull/395 in this release.

Trying to log in to a preexisting node results in:

iscsiadm: No records found


It can be simply fixed by manually moving the directories ( mv /etc/iscsi/{nodes,send_targets} /var/lib/iscsi/ ), but the need to do so is not very discoverable.

I'm not asking to move the database back to /etc, but I think the package's install script should either move /etc/iscsi/{nodes,send_targets} to /var/lib/iscsi/ or at least show a message in post_upgrade.


Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any
open-iscsi 2.1.9-1


Steps to reproduce:
Try to connect to a configured node that was added to the database with open-iscsi 2.1.8-2 or older.
