What are your procedures for updating your Gentoo system without dependency problems.
I usually do:
emerge --sync
emerge --update world

For me it happens from time to time that I need to unmerge packages and reemerge them to go through with the world-emerge. Sometimes I remember to use revdep-rebuild, python-updater and emerge --depclean but its not a part of my "update-process". What is the best process to keep the system updated? Does the order of doing things matter?
Is this example a good process:

emege --sync
emerge --update world
emerge --depclean
python-updater
revdep-rebuild
emerge --update world

How do you do it?

Welcome to the forums jortax

I can't claim to be an expert, my approach is usually ...
I do this fairly regularly and then less regularly I will do
(usually as part of above)
I prefetch files so I know everything should be available for the update and is consistent.

I used to dread running until I got a set of USE flags that worked for me.

Ed: I think it is worth running with -av options so you know what is going to be updated .
It will be interesting to see what more experienced users do

I usually only do
Every once in a while I'll run

I have emerge -uDN world set in a crontab to run daily, and every 2 - 3 days I will run an
I am on a quad so it really doesn't take long to update.

Hi MikeTbob ... why do you do both world & system updates?

MikeTbob

I read this somewhere,,world is different from system and for some reason I still do it every now and then. Here is a link, that kind of explains it....but it's not the link I read awhile back, I can't seem to find that one.

[gentoo-user] Emerge -u system or World ?

How can fail to update packages which will ... unless you manually change world definition?
I can understand updating system without world update can leave packages not being updated but how does this work the other way round? ... is this related to stage1/stage2 tarballs?

... if there is a good reason for running both I'll start doing it

MikeTbob

I'm not sure of the answer here. Maybe someone else could pitch in, I may be doing it for nothing....I seem to remember it did update something a long time ago...but maybe I just ran emerge -u system first. Does emerge -avuDN system want to update any packages on your system?

Glad to hear you're using this: I plan to keep it much more aggressively up-to-date than has been the case in the past, but don't hesitate to let me know if you find errors or need clarifications.

I usually do

emerge --sync && emerge --update --ask world && emerge --update --deep world


If I have altered any of USE flags:
emerge --update --deep --newuse world
emerge --depclean
revdep-rebuild

After transition to new python:
python-updater
