Comment 5 for bug 1657615

Hi Olivier,

After those patches, we still have an issue here in MG5_aMC 2.5.2. The output is:

set golem ''
save options --auto
save configuration file to /afs/cern.ch/sw/lcg/external/MCGenerators_lcgcmt67c/madgraph5amc/2.5.2.atlas.1/x86_64-slc6-gcc47-opt/input/mg5_configuration.txt

and seems to come from L579 of madgraph/interface/loop_interface.py:

                self.exec_cmd('save options %s' % key)

Presumably this should also be protected against a read-only file system?

Our latest installation is here:
/afs/cern.ch/sw/lcg/external/MCGenerators_lcgcmt67c/madgraph5amc/2.5.2.atlas.1/x86_64-slc6-gcc47-opt/

and you can try running yourself to see the same on lxplus, if you would like.

Thanks,
Zach
