Discovered on: amd64 (internal ref: ci) NOTE: This is an experimental tinderbox feature. To reproduce this issue: 1) Install the package with FEATURES=test 2) Put the list of the installed files into a file ( qlist -e PACKAGE:SLOT | sort | uniq > /tmp/qlist_test ) 3) Install the package without FEATURES=test 4) Put the list of the installed files into a file ( qlist -e PACKAGE:SLOT | sort | uniq > /tmp/qlist_notest ) 5) See the diff between the two files ( diff -ru /tmp/qlist_test /tmp/qlist_notest ) On this machine: - the installed files with FEATURES=test are 931 - the installed files without FEATURES=test are 929
