I set up a production server on Gentoo. I regret that now. There are other things to do,and daily emerges to keep it up to date are a scary proposition. I always stayed in the office until everyone left, so if it failed, it could be fixed. When you don't do it daily, it gets even more scary. Now it's been running solidly without updates for over a year... But I don't think it's going to survive an update now. I think Gentoo on a server is a BAD idea.
I've got a server running Gentoo. It syncs the portage tree every week on Sunday via a script, updates any software I've deemed necessary to be updated and it also installs anything which glsa-check recommends to be installed. But it won't update unnecessary software, I've set it up to do the compiling in the middle of the night on the highest possible nice level.. And I just haven't installed anything unnecessary there like GUI software. And it's working like a dream. Haven't had to do anything manually for several months and haven't had any issues with it whatsoever
That's great. (I also only installed what was strictly needed.) I do remember having to etc-update after most updates.
My work place runs Gentoo on production servers too... and I myself runs a Gentoo machine for my daily analysis tasks. We have excellent runtime and we haven't run into a problem yet.
The point is, anyone that runs emerge -u world daily without checking is just asking for trouble. How many people would actually let Ubuntu, Debian, or RHWS auto-update to the next major release automatically on a production server? People would say that those people are idiots.
For me, I never emerge any big packages until it's released for 3 days after stable (let the early adopters install and found the issues for me). For kernels, aside from GLSA advisories, I only wait until -r3 before installing. For critical packages like glibc I wait at least a week before installing.
I always take a quick look before emerges. With the older hardware I run, a "emerge -u world" would probably kill my nvidia-driver for new every new update nvidia put out(for example, nvidia recently decided to change the 1.0.87xx versioning convention into the 87.xx conversion for no reason). So, Gentoo, like other distributions, requires a bit of care when updating.. just that the care is spread out over time rather than one big honking update.
