Not yet, but will try ...
In the mean time, i want to report an installation problem for
execution hosts (with ignore_fqdn=false and default_domain=none).
The installation script "util/install_modules/inst_execd.sh" always
remove the domain part of the host name; which looks wrong, as it
check for dots a little later to eventually append the default domain,
This hostname is not known at qmaster as an administrative host.
Real hostname of this machine: raclette-05.calcul.pasteur.fr
Aliased hostname (if "host_aliases" file is used): raclette-05.calcul.pasteur.fr
Default domain ("none" means ignore): none
Ignore domain names: false
The resulting hostname is: =========> raclette-05
njoly at raclette-05 [adm/sge]> ./utilbin/lx24-amd64/gethostname -all
SGE name: raclette-05.calcul.pasteur.fr
Host Address(es): 18.104.22.168
I checked that the attached patch fix that problem.
