I've just got this after an emerge -u @world !!! existing preserved libs: >>> package: dev-libs/icu-50.1-r2 * - /usr/lib64/libicui18n.so.49 * - /usr/lib64/libicui18n.so.49.1.2 * - /usr/lib64/libicuio.so.49 * - /usr/lib64/libicuio.so.49.1.2 * used by /usr/sbin/cgdisk (sys-apps/gptfdisk-0.8.5) * used by /usr/sbin/gdisk (sys-apps/gptfdisk-0.8.5) * used by /usr/sbin/sgdisk (sys-apps/gptfdisk-0.8.5) * - /usr/lib64/libicuuc.so.49 * - /usr/lib64/libicuuc.so.49.1.2 * used by /usr/sbin/cgdisk (sys-apps/gptfdisk-0.8.5) * used by /usr/sbin/gdisk (sys-apps/gptfdisk-0.8.5) * used by /usr/sbin/sgdisk (sys-apps/gptfdisk-0.8.5) * - /usr/lib64/libicudata.so.49 * - /usr/lib64/libicudata.so.49.1.2 Use emerge @preserved-rebuild to rebuild packages using these libraries * After world updates, it is important to remove obsolete packages with * emerge --depclean. Refer to `man emerge` for more information. You won't see that because the subsequent programs run by your alias will scroll it out of view. The important point is that although the library update could have broken gptfdisk, it didn't because portage is holing onto the old library until I have run emerge @preserved-rebuild. Contrast this with the previous approach of letting emerge break important software and relying on revdep-rebuild to get it working again. -- Neil Bothwick All things being equal, fat people use more soap.
