 Posted: Tue Oct 15, 2024 3:53 am Post subject: emerge usage that is confusing |
 |
|
Hello,
I am checking for updates every morning using these steps:
| Code: | emerge --sync
emerge -auUDv --with-bdeps=y @world
emerge --ask --depclean
dispatch-conf |
I have arrived at those steps while I was reading on the update/upgrade procedures. Would this usage be correct?
What got me confused is, two days in a row, there were no updates for my system. Then I went to the https://wiki.gentoo.org/wiki/Upgrading_Gentoo page and saw some comment like this
| Quote: | root #emerge -avuDN @world
--changed-use may be used in place of --newuse, but only if you do not build binary packages. --changed-use will not trigger reinstallation when disabled USE flags are added or removed from a package. See the Binary package guide. |
When I did emerge -avuDN --with-bdeps=y @world I had 3 reinstalls. But emerge -auUDv --with-bdeps=y @world does not show any updates.
I want to have my system up to date. And since I only emerge a couple of binary packages (firefox-bin, google-chrome, and libreoffice), and do not build them (as binary packages), I should use --newuse I believe. Would that be correct?

Make sure you check the news items, too.
Here is a topic which may shed some light about the emerge --changed-use vs --newuse question: https://forums.gentoo.org/viewtopic-p-8719502.html |
I got that habit from using a rolling release system prior to gentoo. You might be right about the overkill.
Thanks for the information on --changed-use and --newuse.

Based on the comment in here: https://wiki.gentoo.org/wiki/Gentoo_Cheat_Sheet#Package_upgrades
| Quote: | Package upgrades
Upgrade all packages in the world set, their dependencies (--deep), and packages that have USE flag changes (avoiding unnecessary rebuilds when USE changes have no impact):
root #emerge --ask --verbose --update --deep --changed-use @world
The --newuse may be used in place of--changed-use to make sure that all package use flags reflect the current state of those in the Gentoo repository, though this will entail more rebuilds. The --with-bdeps=y can be used to update build time dependencies also. |
I think I will be using the --newuse option. I would like to keep the use flags to be the same as they are in the gentoo repo's. Would not mind more/extra rebuilds. But will be checking both --changed-use and --newuse when updating my system to see if these agree with each other. |
