That is reason why we introduce idea of simple git tarball and
using osc to do all generation, building and other steps.

Just create a VM in the cloud, start the correct image, do the
packaging and delete the VM again. Isn't that the whole idea of
the cloud?

Yes, you could use cloud, but it's too complicated. Running a
special VM just to create a simple tarball from Git checkout sounds
crazy to me...

You can also run unit test, code coverage and some integration
tests in the VM. Apart from that the VM is not so special, just
the standard SDK is needed.

unit tests should be run in test phase of build process, so osc build
should do it for you with all required libraries.
Code coverage is a bit tricky, but you usually do not do it on jenkins
just for code submission. For integration testing it is needed to have
proper env, but it require to really maintain such VMs, which is a bit
time demanding.

Just consider you have security fix that goes to SLE11 SP1, SP2, SP3,
SP4 and SLE12 GA, in your way you have to start 6 VMs which
have to be updated. with git tarball and osc approach, you do testing
just once or twice ( 11 and 12) and rest is covered by unit tests in
test phase.

Remember what you need to do if you want to build an YaST package
for SLE11 - you need installed yast2-devtools in the appropriate
version + all tools used (like autoconf, automake,...) + the needed
libraries. You need different set of packages for each SP release,
that's too complicated even with the help of VMs.

Don't think about all the different packages but about a
different distribution. Then it is not complicated at all. I
always do development for old distributions in VMs. You need them
for testing anyway.

And you need also to maintain it and whats more, if other need to do
some development, then it is a bit tricky to set it up correctly. Just
stop thinking for a moment about snapper and libstorage. Imagine that
we need urgent fix for yast2-ruby-bindings and you as C++ expert look
at it and fix it.
Is easier for you to do

git clone
hacking/writing unit test
rake osc:build

Or use proper VM, set properly cmake, install all required packages in
proper versions, create a tarball ( in cmake very tricky as there is at
least three different commands that can do it and result is different
), generate spec file and then copy it to osc checkout directory?

I think majority of team prefer first way and are happy with way how is
easy to submit now yast/libyui packages.
