Besides these questions, the transition from revdep-rebuild to @preserved-rebuild may be worth a note as well; if I remember correctly you have to do one last revdep-rebuild when you enable this feature, or in other words preserve-libs won't detect present inconsistencies. I feel like this should probably be documented as well, as part of mentioning that this is intended to replace revdep-rebuild... -- With kind regards, Tom Wijsman (TomWij) Gentoo Developer E-mail address : tom...@gentoo.org GPG Public Key : 6D34E57D GPG Fingerprint : C165 AF18 AB4C 400B C3D2 ABF0 95B2 1FCD 6D34 E57D
