Hi,

the discussion about sumo triggered me to take a look at this tool to figure 
out if it can helm me to solve a problem I currently have. I need to setup a 
procedure to roll out a set of EPICS modules for a project that will be 
installed also off site by inexperienced persons. And looking at the 
documentation sumo would exactly do what I need. I would configure my IOC 
application using sumo and the locally installed modules. Then I would roll 
out the application together with the sumo config files and it would be a few 
well documented steps to get the IOC compiled an running.

Currently I have a set of shell scripts, a set of patches for the 
configuration files and a Makefile to do the job. But as the configuration 
files change with every new release, I need to create the patches on a regular 
basis. That step I would like to get rid off. 

So I installed all EPICS modules I need, together with base in the directory 
structure needed by sumo (modules/src/<module name>/<module version>).
Then I ran sumo-scan on the modules directory to get the configuration. All my 
modules where clonedout from github and the latest tag was checked out. Much 
to my surprise sumo-scan put all modules as "path" type, only areaDetector sub 
modules (besides aravisGigE) where detected as "git" repositories.

Looking with "sumo-scan -t" at what is done during the process, Isee a small 
difference between the areaDetector and all other modules:

git -C .../modules/src/areaDetector/3-7/ADSupport status --porcelain

returns nothing, while e.g. 

git -C .../modules/src/iocStats/3.1.15 status --porcelain

returns 

 M configure/RELEASE

Which I needed to change to be able to define all the depended modules.
So here I#m stuck. Do I realy have to create the dependency file by hand?

Any tips and ideas welcome!

Regards
