need help updating system

[blakdeath]

I understand the -u updates the system, so now I need to run
emerge -u world to update my system, which is fine, however the handbook is a little cryptic imo when it comes to USE flags when updating
I always use USE="<use flags>" when emerging ANY package, so almost all my packages are using the non default USE flags

when I need to preserve the use flags for the updates, do I use --newuse or --changed-use
or is there another option



thanks

You should consult the man pages, because the options don't do what you think they do. --newuse specifically looks for packages with use flag settings are different from the ones on the system, so invoking that option destroys all your command line modifications. You should generally never use USE="flags" because it is non persistent. Portage will never respect these during an update.

Global use flags should go in /etc/portage/make.conf Package specific ones should go in /etc/portage/package.use (you will need to create the file.) Use the following format <catagory>/<pacage> <flags>

Also note the color code portage uses. Red flags are active, blue flags are inactive and green flags which have changed from the previous install.

thanks for the heads up
and the colour part was EXTREMELY USEFUL

blakdeath Unless you store how you want the USE flags set in one of the config files, the next time you update those packages, you will loose those settings.

I'll use that next time i mix things up
thanks
