P.S. I wrote this before reading John Crisp'comment. I am very sorry to have started that exchange of "words". I just wanted to help a friend who asked me about SME & ERP.

Michel,
you didn't. Someone else did. I am very sorry that it descended the way it has. I was merely trying to point out - and as a user since 5.x I am sure you know this already - there is an accepted way of doing things here. That was set in stone before I was here.
Regrettably a certain poster has a historical axe to grind and is happy to do so publicly and as often as possible. It is unfortunate, and quite frankly embarrassing.
As a collective we understand that our users usually seek stability over cutting edge, and that has always been the nature of the distribution.
I can assure you, and anyone else reading this, that we want nothing more than to help users and to ensure a first class, secure, and stable distribution, and therefore we try to discourage people from doing things that
may break their system unless they fully understand what they are doing, or are trying to do it as a development project. And in which case the best place to discuss it is the developers list mailing list - do please join it and ask away - or bugzilla, and we are only too happy to help people who want to help themselves and others in a constructive fashion, despite what has been said.
No, not every developer may agree with what you say, or how you want to do it (which is what upset the other poster in the first place), but it is the best place for the discussion. The way forward is always a compromise, and there will always be some differences of opinion. Sometimes we have to agree to disagree, and move on

I am certainly no expert, and have never pretended to be. Nor do I assume the level that other users may have when advising them, so the mantra is always keep it simple, don't do anything that might break your system. If you do advise something that is non standard then advise the user that they
may encounter problems.
Quite frankly we have enough bugs to deal with without people installing other repos and then breaking things - we see plenty enough of that already and do not need to add to the pile..... !!!! Unfortunately despite their undoubted intelligence and skill, the other poster never gets involved in fixing anything, and therefore he wouldn't know or care about that.
As I advised you, we support the distribution that we produce, though we are obviously bound by upstream issues if they exist.
Once you start to diverge from our or the standard upstream repos then we start to have a problem, hence my comments. We obviously cannot support every repo and package out there.
Once again, let me assure you that we want to help users in any way we can. What we don't want is people breaking their systems !
I do hope that you will post any results of your endeavours on the wiki. Should you need more help then please join us on the devinfo list here :
http://lists.contribs.org/mailman/listinfo/devinfoYou can also email me personally should you have any other questions.
One again, please accept my apologies for the problems here. This is NOT what the distribution wants to see. It is divisive, non-pedagogic (

) and does no one any good.
Kind Regards,
John Crisp
