Run successfully when /var or /var/tmp is a symlink
-
pv-wrap: Print FlatpakExports as we process it
-
pv-wrap: Delay --dir, etc. until after FlatpakExports are processed
If the FlatpakExports has set these up to be symlinks, it's harmless to use --dir redundantly; but if we do these too soon, the FlatpakExports would be unable to create its symlinks and would fail.
