Some binaries move from /bin to /usr/bin with a coreutils-6.7 update. That means that all scripts and cronjobs with hard coded pathes will fail to work. I observed this problem with ./cron.weekly/slocate and ./cron.daily/makewhatis because /bin/nice is no longer found. Hell knows what else is broken. I wonder how this crude ebuild made it's way into stable, at least a enotice would have been nice. :( Reproducible: Always
