FEATURES=test emerge -1va appstream-glib is now putting files into /tmp and leaving them there. At least the following extra subdirectories (with files inside) end up in /tmp even after emerge is done: drwx------ 2 portage portage 60 28. juuni 01:33 32x32 drwxr-xr-x 4 portage portage 80 28. juuni 01:33 destdir -rw-r--r-- 1 portage portage 2814 28. juuni 01:33 foo.png drwx------ 3 portage portage 60 28. juuni 01:33 origin I think that's the usr test data folder from the tarball or something (probably tests are written there and then compared to what's shipped or something). Need to convince its meson build to use portage tempdir for this stuff..
