Created attachment 532104 [details, diff] Ebuild patch enabling the correct savedconfig support x11-misc/sent declares the savedconfig USE flag but it never calls save_config and the restore_config call targets the example config (config.def.h) instead of the proper one (config.h). I am attaching the proposed patch, generated against x11-misc/sent-1 but should be relevant to all the other x11-misc/sent versions too.
Fixed in -r1 and 9999. Thanks.
