Have you ever updated your world or system and walked away only to come back several hours later to find out the update did not complete because a package failed?
The following simple command list and bash 'until' command will let you update your world or system to completion and skip those packages that failed:
Code Listing 3.1: Using until to skip broken packages
# sudo emerge -Du world ||
# until sudo emerge --resume --skipfirst; do
# sudo emerge --resume --skipfirst; done
Once the command list completes, you can find out which packages failed by running the following command:
Code Listing 3.2: Checking for failed packages
# emerge -Dup world
Warning: Under certain circumstances, this can yield an unusable system. Always check the output of emerge -Dup world prior to using this tip. |
