Not something I take lightly, nor is it something I look forward to doing. \u00a0In Gentoo the emerge “-e” means rebuild all packages installed on the system that portage has recorded. \u00a0A quick ‘equery -l “*”‘ will list all packages installed.<\/p>\n
So why do I do this every year or so? \u00a0Just to make sure I have not messed something up over time. \u00a0It is not something I look forward to because the time from start to finish is measured not in hours, but days. \u00a0For example, it took my i7 laptop (1,400+) packages with SSDs and plenty of ram 24+ hours to finish. \u00a0However, in the end I was confident the system was in good shape.<\/p>\n
So here are my tips at making this painful experience a little less painful.<\/p>\n
1. \u00a0I start by getting the system in the best shape possible:<\/p>\n
emerge -v –update –deep –newuse –with-bdeps=y –autounmask-write @world<\/em><\/p>\n If needed:<\/p>\n emerge @preserved-rebuild<\/em><\/p>\n then:<\/p>\n emerge –depclean<\/em><\/p>\n If you are paranoid careful then do:<\/p>\n python-updater<\/em><\/p>\n perl-cleaner –all<\/em><\/p>\n 2. Next: \u00a0cd \/var\/log\/portage\/elog<\/em><\/p>\n You should find the file summary.log. <\/em>\u00a0Rename it or delete it, whatever suites you. \u00a0Once the big emerge starts, all the messages will be logged to a new\u00a0summary.log<\/em>\u00a0file.<\/p>\n 2. Execute: \u00a0\u00a0emerge -pve –keep-going @world<\/em><\/p>\n Note the “p” for pretend. \u00a0If everything is good then it should tell you that the Oracle Java packages need to be downloaded. \u00a0This is a good time to download them (I have Jre and jdk packages installed), move them to portage\/distfiles, and do not forget:<\/p>\n chown portage:portage <file>\u00a0<\/em><\/p>\n to the files. \u00a0Make a mental note of the total number of packages to build.<\/p>\n 3. Start by executing: \u00a0emerge -ve –keep-going @world<\/em><\/p>\n Why the keep-going? Because if everything is good after step 1 then any issues should be minor and this keeps from having to start the process from the beginning.<\/p>\n Now all there is to do is wait and hope for the best which usually does not help. \u00a0As the emerge progresses with each new package the typical package number X of Y (total) being processed. \u00a0So if you start with a total of 1,400 packages and later notice emerge outputting 20 of 800 then there has been a problem which has been skipped (note: \u00a0the –keep-going option). \u00a0Go check the\u00a0summary.log\u00a0<\/em>file to find what the problem might have been. \u00a0The best part is that you should be able to fix it while the emerge -e keeps churning along.<\/p>\n Enjoy!<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Not something I take lightly, nor is it something I look forward to doing. \u00a0In Gentoo the emerge “-e” means rebuild all packages installed on the system that portage has […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"_links_to":"","_links_to_target":""},"categories":[12,29],"tags":[57,69],"class_list":["post-159","post","type-post","status-publish","format-standard","hentry","category-gentoo","category-portage","tag-gentoo","tag-portage"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":89,"url":"https:\/\/www.mgreene.org\/?p=89","url_meta":{"origin":159,"position":0},"title":"Gentoo Java emerge issue","author":"Mike","date":"February 8, 2015","format":false,"excerpt":"Once again portage tells me there is an Oracle Java update and I already know it will have to be downloaded manually and moved into \/usr\/portage\/distfiles.
