Hi,
a new version of a (binary) package I'm maintaining (clockify-desktop) requires
an
executable /tmp directory to run.
My immediate questions would be why, and is this an upstream issue?
Or, is an executable /tmp a reasonable assumption? 🤔
I don't see anything in file-hierarchy(7) that mandates an executable
/tmp. That said, it contains a hint that some programs might break:
      /tmp/, /var/tmp/ and /dev/shm/ should be mounted nosuid and
      nodev, which means that set-user-id mode and character or block
      special devices are not interpreted on those file systems. In
      general it is not possible to mount them noexec, because various
      programs use those directories for dynamically generated or
      optimized code, and with that flag those use cases would break.
      Using this flag is OK on special-purpose installations or systems
      where all software that may be installed is known and doesn't
      require such functionality. See the discussion of
      nosuid/nodev/noexec in mount(8) and PROT_EXEC in mmap(2).
