Arch = ~amd64. I have virtual/logger in @world which previously pulled in app-admin/syslog-ng (which is not in @world). Busybox is in @system by default with default flags (notably USE=syslog). emerge --depclean now wants to remove syslog-ng, presumably as busybox[syslog] satisfies the virtual. This is an incorrect evaluation as this is not an embedded system, busybox is not the usual userland and busybox only runs when attempting a rescue. This is a regular workstation so it is incorrect to have busybox[syslog] satisfy virtual/logger for this general case. I suggest busybox only satisfy this virtual is cases where busybox is the userland and some mechanism be implemented to indicate this to portage. The cause appears to be #444718. I will add syslog-ng to worls to make --depclean shut up, but the logic in code is still incorrect as I should not have to do this. Reproducible: Always Steps to Reproduce: 1. emerge virtual/logger to @world 2. emerge sys-admin/syslog-ng but do not add to @world 3. emerge busybox[syslog] to @system Actual Results: emerge --depclean wants to remove syslog-ng Expected Results: emerge --depclean should not remove syslog-ng in cases where busybox will not be runnign in normal conditions # emerge -at --depclean Calculating

If you want to keep any package on a system, regardless of whether it is temporarily conveniently insured to be installed by a virtual that happens to depend on it and its alternatives, then the place to secure this is the world file.
