Description

On some systems (especially AIX), the hostname in the inventory is always on lowercase; which is wrong
Command

/opt/rudder/bin/rudder-perl -e "use Sys::Hostname; print Sys::Hostname::hostname();"

returns the proper hostname, while sys.fqhost returns an hostname with invalid case

We should use the perl approch, when available (not on Android then) for the hostname

another solution could be to use hostname in fusioninventory inventory

Target version changed from 2.11.12 to 3.1.0~rc1

this change is too big to go to 2.11, but it would go in 3.1: it is safer to use reliable hostname from fusion inventory

Oh ... the Rudder extension in Fusion inventory contains the hostname (but it is only on linux)

In OPERATINGSYSTEM/FQDN we have the fqdn of the node, which exists on AIX, Windows, and is correctly filled (using http://search.cpan.org/~gbarr/libnet-1.22/Net/Domain.pm )

according to fusioninventory team, HARDWARE/NAME should be the right one

OPERATINGSYSTEM/FQD should have the correct content

However, i'm puzzled by current parsing:
we parse the inventory, and if we have HARDWARE/NAME, we set the node name to this value
then if we have Rudder expansion, we parse them, and use RUDDER/HOSTNAME

the deprecated HOSTNAME seems to be never used

Ha, Vincent gave me some more info on this point:
- OS/NAME is not used as the hostname, but as the node.name (tricky...)
- Main value for hostname is RUDDER/HOSTNAME.
- If RUDDER/HOSTNAME doesn't exist, then we use HOSTNAME

HOSTNAME is always lowercase, while RUDDER/HOSTNAME has the proper case

What we want: something consistent
OPERATINGSYSTEM/FQDN is always consistent (proper case with the proper fqdn)
RUDDER/HOSTNAME has the proper case (but without the domain name always, as it uses hostname --fqd that may work per chance (as the proper attribute is --fqdn))
HOSTNAME is always lowercase, and may, or may not, have the domain name
HARDWARE/NAME has the proper case, but without the domain name

So, we should pick OPERATINGSYSTEM/FQDN if available, if not RUDDER/HOSTNAME, if not HARDWARE/NAME

Ok, for sanity, we only pick OPERATINGSYSTEM/FQDN
So that we are ensuring consistency of value, it is easier, less error prone, and this value exists since in along time in fusion
