Installing packages via apk sometimes installs empty files
I was trying to install python2 and rsync. Running
apk add python2 created a symlink named python2 to an empty file it created named python2.7. Running
apk add rsync created a file named
rsync that had the same size as the
rsync binary, but running hexdump on it revealed it to be full of zeros.
The workaround for now was to uninstall those packages with
apk del and reinstall.
