The gudev USE flag is deprecated from systemd, and the functionality is now provided by libgudev (see bug 552036). However, i get the following block;
# emerge -a1 =sys-apps/systemd-226-r2 dev-libs/libgudev These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild N ] dev-libs/libgudev-230 USE="introspection -debug (-static-libs)" ABI_X86="(64) -32 (-x32)" [ebuild U ] sys-apps/systemd-226-r2 [218-r5] USE="kdbus* -gnuefi% -importd% -nat%" [blocks B ] sys-apps/systemd[gudev(-)] ("sys-apps/systemd[gudev(-)]" is blocking dev-libs/libgudev-230) So i plan to emerge libgudev with nodeps (to avoid the blocker), then upgrade systemd which will of course build without the gudev flag and I think I should be ok. Do I understand correctly?
