[PATCH] isar-installer: show progress bar during bmaptool copy process

[PATCH] isar-installer: show progress bar during bmaptool copy process

['Kasturi Shekar' via isar-users]

- Added support for a progress gauge using a named pipe to capture and display
 percentage progress when using `bmaptool`.
- The progress bar is displayed only when the `bmaptool` version is 3.8 or above,
 as versions prior to 3.8 has some issues with `--psplash-pipe` flag.
- For `bmaptool` versions below 3.8, the image copy process continues without a
 progress bar to maintain compatibility.
- The gauge uses `dialog --gauge` to dynamically update the progress based on
 output from the `bmaptool` process.

Which issues were these? Is there some related upstream or Debian bug?

3.8 means trixie, just to clearify.

This should be possible as well:

version_ge() {
        if [ "$(printf '%s\n' "$1"X "$2" | sort -V | head -n 1)" != "$1"X ]; then

The version tests are done above - commenting here is a bit confusing.

Yes, it’s a Debian issue and 3.8 is Trixie.

Kasturi, please fix your email client settings so that you are inserting
proper citation markers ("> "), and your answers become easier
distinguishable.

Felix, did you try to motivate upstream for a stable fix as well?

Please always version our patches, or you will only create confusion for
reviewers and maintainers. This would be "PATCH v5" now.

[PATCH] isar-installer: show progress bar during bmaptool copy process

['Kasturi Shekar' via isar-users]

- Added support for a progress gauge using a named pipe to capture and display
 percentage progress when using `bmaptool`.
- The progress bar is displayed only when the `bmaptool` version is 3.8 or above,
 as versions prior to 3.8 has some issues with `--psplash-pipe` flag.
- For `bmaptool` versions below 3.8, the image copy process continues without a
 progress bar to maintain compatibility.
- The gauge uses `dialog --gauge` to dynamically update the progress based on
 output from the `bmaptool` process.

I would not use dpkg -  as bmaptool has a `--version` option.
