Description

in #2443 we introduced a change for storing policy server uuid (was in /var/rudder/tmp/uuid.txt in 2.11, changed in 3.0)
The Fusion Inventory in Rudder 2.11 still uses this path however, even if promises are 3.0 (so not updated)

If a 2.11 node, which had a 2.11 Rudde server, now has a 3.0 server, the file /var/rudder/tmp/uuid.txt will never be updated
So even if the promises set the correct uuid in the rudder extension, the fusion inventory one prevails and will never be updated

Erasing the /var/rudder/tmp/uuid.txt solves the issue

So, in Rudder 3.0 tehcnique, we should purge this file if it exists

Additional information:
- In Agent 2.11.X (X<13) the Rudder.pm adds the Field POLICY_SERVER_UUID populated from tmp/uuid.txt.
- In the promises for 3.0.X FusionAgent.cf contains logic to add a POLICY_SERVER field via edit_line bundle, populated from ${sys.workdir}/rudder-server-uuid.txt

This results in an inventory like for example:

<POLICY_SERVER_UUID>78169036-10f9-11e5-b8f7-afb7081228de</POLICY_SERVER_UUID>
<POLICY_SERVER>238ea28e-629c-11e5-acae-6a81cf67da3d</POLICY_SERVER>

From which apparently the POLICY_SERVER_UUID takes precedece over POLICY_SERVER (if that is set).

A solution is to remove the tmp/uuid.txt, which will result in a perl error, since the file being opened does not exist:

Q: "...-inventory --lo": [error] Can't open file /var/rudder/tmp/uuid.txt: No such file or directory
Q: "...-inventory --lo": Use of uninitialized value $serverUuid in scalar chomp at
/opt/rudder/share/fusioninventory/lib/FusionInventory/Agent/Task/Inventory/Linux/Rudder.pm line 71.
Q: "...-inventory --lo": [info] Inventory saved in /var/rudder/tmp/inventory/linux-03ce7386-0c2d-11e5-a06b-25e1081228de.ocs
Q: "...-inventory --lo": [info] task WakeOnLan execution not requested
Q: "...-inventory --lo": [info] task NetDiscovery execution not requested
Q: "...-inventory --lo": [info] task NetInventory execution not requested

But the resulting inventory would reflect the change of PolicyServer in the WebUI.

However, this change is not reflected by starting a regeneration of policies for the node, see for that #8046
