And prelink still messes up "rpm -V" output. rpm -Va has become pretty useless since prelink was added. I know it is supposed to un-prelink on-the-fly to do the verify operation via prelink --verify, but this doesn't seem to work much of the time. rpm -Va from an F9 system: prelink: /usr/lib/libnetembryo.so.0.5.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libnetembryo.so.0.5.0 prelink: /usr/lib/libdvbpsi.so.5.0.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libdvbpsi.so.5.0.0 prelink: /usr/lib/libwx_baseu-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libwx_baseu-2.6.so.0.4.0 prelink: /usr/lib/libwx_baseu_net-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libwx_baseu_net-2.6.so.0.4.0 prelink: /usr/lib/libwx_baseu_xml-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libwx_baseu_xml-2.6.so.0.4.0 prelink: /usr/lib/libwx_gtk2u_adv-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libwx_gtk2u_adv-2.6.so.0.4.0 prelink: /usr/lib/libwx_gtk2u_core-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libwx_gtk2u_core-2.6.so.0.4.0 prelink: /usr/lib/libwx_gtk2u_html-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libwx_gtk2u_html-2.6.so.0.4.0 prelink: /usr/lib/libwx_gtk2u_qa-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libwx_gtk2u_qa-2.6.so.0.4.0 prelink: /usr/lib/libwx_gtk2u_xrc-2.6.so.0.4.0: at least one of file's dependencies has changed since prelinking prelink: /usr/lib/libnemesi.so.0.604.0: at least one of file's dependencies has changed since prelinking S.?..... /usr/lib/libnemesi.so.0.604.0 etc. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
