[rb-general] [Debian] just how do you set the umask that setting it back to 022 doesn’t work?

Yes, try zipinfo(1):

  $ zipinfo -v path/to/Advanced.workspace | fgrep 'Unix file'
    Unix file attributes (100644 octal):            -rw-r--r--
    Unix file attributes (100644 octal):            -rw-r--r--

One can confirm that this is the tool used by diffoscope (which, as an
aside, definitely resets its own umask…) here:

  │ ├── data.tar.xz
  │ │ ├── data.tar
  │ │ │ ├── ./usr/share/mscore3-3.2/workspaces/Advanced.workspace
  │ │ │ │ ├── zipinfo /dev/stdin
              ^^^^^^^

Hopefully we can keep this list friendly and welcoming to all
regardless of your understandable frustration.
