Hi Carlos,
Thank you very much for letting us know, we need to think it deeply :)
Just one question, which are the pros and cons of compiling oned? It is
a serious thing for us since the infrastructure is on production and I
am not sure if it will break future updates trough yum/rpm and also, if
we could break something in current ON installation at CESGA.
Personally, I don't like this decision but it is my humble opinion and
in any case, we need to discuss about it.
Thanks in advance,
Esteban
