Mario and Jacek,

This solution seems very reasonable to me.

An other solution is to use a second repo named 
https://dev.lsstcorp.org/cgit/contrib/eupspkg/qserv.git/ with the TaP 
feature.
And use next procedure :

- copy the tarball from the LSST/DMS Qserv branch beeing packaged to 
contrib/eupspkg qserv/upstream, using git archive
- copy the ups/ directory from the LSST/DMS Qserv branch beeing packaged 
to contrib/eupspkg qserv/ups
- update tag in contrib/eupspkg qserv/ups (this repo is used only to 
create distserver, so less conflicts are possible)

It is more sure, but also much more complicated.
Furthermore, I would like to use the same procedure that for other LSST 
packages (don't you need to update tags in order to update a distributed 
version without impacting its version number ?)

Thanks,

Fabrice
