Description Pacho Ramos gentoo-dev 2017-01-16 12:01:52 UTC
Currently I see a message like this:
>>> package: sys-libs/db-4.8.30-r2
 *  - /usr/lib64/libdb-4.8.so
 *      used by /lib64/security/pam_userdb.so (sys-libs/pam-1.2.1)
 *      used by /usr/bin/bogofilter (mail-filter/bogofilter-1.2.4-r1)
 *      used by /usr/bin/bogotune (mail-filter/bogofilter-1.2.4-r1)
 *      used by 4 other files

But, how could I get for reading all the files that need it without needing to progressively re-emerge the listed packages until I can see all the hidden files? Could that be suggested in the output?

Thanks a lot!

The assumption is that you'll use @preserved-rebuild, but we can add a new emerge action to display the output that you want. Maybe call it --check-preserve-libs.

Yes, we can suggest along with the "Use emerge @preserved-rebuild to rebuild packages using these libraries" message.

Nice, well, not sure about the naming... but that is not a big issue. It will be useful to me for knowing what packages likely need to be checked for right := deps for solving them for the far future when the soname is bumped again
