Help needed with E3

[Jörn Dreyer via Tech-talk <tech-talk at aps.anl.gov>]

Hello folks,

after experimenting with SUMO I also tried the E3 framework from ESS and found it very usefull.
It installed without problems on my OpenSuSE Tumbleweed system and compiled the basic modules that I need for my installation without problems.
I also managed to write wrappers for my modules within a few day's but stumbled across some problems for which I do not have a solution yet.

One of my modules needs a small kernel module like the mrfioc2 module. When calling "make dkms_add" it failed because the variable SUDO that
is used in the RULES_DKMS_L file is not defined. Defining this externally made the installation possible but the build with "make dkms_build" failed
because that is not called with the $SUDO prefix. 
As I do not have a CentOS installation available, I can not check how the default configuration is there. So I can not tell if this failure comes from
my specific Linux distribution or it is off more general origin. 

The second topic I would like to get some help with is the specifications files. As the documentation for this file is ESS internal only
I could not find a solution how to extract the  correct time information of the git commit that is part of the module version information.

This directly leads to the third problem of how to integrate local modules into the automatic build process of "e3 build".
The default is using gitlab.ess.lu.se only to search for the wrappers. But looking at the source code of e3 it looks as there could be a third parameter
to the module version defining the repository from where to take the module.
Did anybody use E3 outside of ESS with local managed modules and wrappers or knows how to configure it to use a specific repository?

If I manage to get that to work, I would recomend the tool to be used for our upcoming accelerator control system which will be based on EPICs.

Kind regards
