Hi,
I´m trying to upgrade portage because I´m getting a message that it
needs to be able to work with EAPI 6 packages and can only do EAPI 5.
I´m running into merge conflicts when trying to update portage, and
apparently one of the packages (dev-python/cryptography) I could try
to update first to be able to update portage requires a version of
portage that can handle EAPI 6 packages.
Try the other suggestions first -- but as a last resort -- you can
always grab a new stage3 that should contain an updated version of
portage and simply overwrite the portage files on your machine. A
quickpkg from another Gentoo machine (or the liveCD?) would also work.
I´m trying to update a production server here. If I overwrite the whole
system, who knows what might break. I can take it down for a few
hours in the evening unless I want to work over night, which is not
really an option.
There must be a way to update a Gentoo installation without breaking it.
As wonderful as it otherwise is, updating Gentoo is always a nightmare
which
makes me very seriously consider not to use it anymore. Updating needs to
be easy and flawless and not something you always run into weird issues
with.
When I run gentoo as a critical server, I always have a second,
redundant system pretty much identical, on stanby. I upgrade the stanby
first and run it a few days, then the production system. It makes
reliability extraordinarily high. But, the again, I do a version of the
same thing with all critical systems, or I do not work on them. Granted,
as successful consultant, I have that luxury.
Did they recently make a new liveDVD?
A few months ago.

Perhaps a better solution is to make a stage-4, of your current gentoo
(production) system, verify that the stage-4 works by using it to
install a similar system, test and deploy. And then hack or fix the
production system, during the daytime, at your leisure?
Stage-4 gentoo systems have been around a long time. Documentation
varies and most have their own 'home spun' approach to stage-4 replicant
systems, backups etc etc.
