versionning the vle.conf configuration file

[Chabrier]

In order to have many version of vle installed on the same user account, it could be convenient to distinguish the vle.conf configuration file.

Problem comes from the VLE_COMMAND_VLE_SIMULATION (executable name: vle-$VLE_ABI_VERSION) [1]. User must use the --restart command line option to rewrite the vle.conf file between VLE 2.0 and VLE 2.1 otherwise, the VLE executable use can be the wrong.

Solutions are:

• suffix $VLE_HOME/vle.conf: vle.conf for VLE 2.0 and vle-21.conf for VLE 2.1, vle-22.conf for VLE 2.2…

  • The simplest to develop.
  • But, requires to change all the files (vle.log, gvle.log etc) too.

• add a suffixed sub-directories in the VLE_HOME directory. For example, VLE_HOME=/tmp => /tmp for VLE 2.0 (untouched), /tmp/vle-21/ for VLE 2.1, /tmp/vle-22 for VLE 2.2… VLE 2.0 untouched and keeps the current behaviour. Start from VLE 2.1, we add a sub-directory vle-21 where we store binary packages, log, conf etc.).

  • Need change and information for user
  • The least restrictive solution for the future

@rtrepos @Chabrier, I prefer the second solution. It's good for you?
