Good catch. Sorry I missed that. I suppose I've forgotten that a lot of people still use MySQL, even for python. :)
The question "why even have an OS?" was a rhetorical one, meant to illustrate the fact that the argument here is over where one draws the line, between the dependencies you maintain yourself and those you outsource to your OS vendor. Unless you're deploying on Linux From Scratch then you are outsourcing to the vendor at some level, so the only question is, where is that level?
That this guy maintains even his own web and database servers means wants/needs to control things at a much deeper level than is typical. And I think that's beautiful if it works for him. My point of disagreement is his use of the word "antipattern" to suggest that any other choice is wrong.
First of all I’m afraid the point about Apache & MySQL is misleading and I’ll have to clarify it: We don’t use neither for internal projects. It’s all PostgreSQL. :)
They’re both for our customers as we sell traditional web hosting with a LAMP stack (and yes, we have to compile PHP ourselves too, so we can offer different flavors).
I never said you _have_ to compile everything yourself. In case of Python I said you shouldn’t inflict the pain of programming Python 2.4 just because you’re on RHEL/CentOS 5 or earlier.
System packages have several problems I outlined too. Most important: you add a middleman to the release pipeline, no virtualenv and possible dependency conflicts: I have apps that depend both SQLAlchemy 0.6 and 0.7 – they couldn’t run on the same server.
But OTOH we use stock packages as far as possible, because it’s less work. Eg. there’s no reason to compile an own Python on Oneiric and later. Same goes for PostgreSQL which is uptodate.
It’s all about freeing yourself from constrains in points that matter, not adopting a new religion.
