Can access to Openvario-Shell Applications and Settings menus or items be restricted for maintenance purposes?

[dpluigi]

Hi all, hi Andrey "Kedder",

An LS4 (with Stefly's OpenVario, sensor board, and remote stick) was purchased by my Club in the French Alps. I was tasked to adjust XCSoar pages and the stick buttons programming to dumb the user interactions down for the pilots new to XCSoa/OpenVario and less experienced xc pilots.

It would be great to lock the access to the Applications and Settings menus on OV-Shell for maintenance purposes on this club glider by an authorized user. In other words, we'd like to prevent user access to some sensitive features on the menu to a strict minimum and be limited to downloading XCSoar logs and uploading task or waypoint files. Dirk "Blaubart" suggested that this is not possible without changing the programming of the menu. The answers and clarifications to the Questions below would help get started with addressing these requirements.

Can "Download Logs" (XCSoar) feature be moved from the "Applications" to the "Main Menu"?

In addition, is there a possibility (then) to have a password/PIN code for selected or sensitive items or Menu levels?

Backup/Restore feature is great for the maintenance of the OV system. As an alternate or in addition to this feature can there be an equivalent limited to XCSoar so that there is no risk of messing up settings for OpenVario, Sensorboard, wifi, ... (also saved in openvario\backup\home\root)?

Note that I had a go at setting up a development environment to compile and test ov-shell with the Ubuntu 22.04.1 LTS distribution (I use it for compiling XCSoar for different plateform), and I wasn't able to compile or run Openvario-Shell.
What would be a recommended Linux distribution and build / test environment on a PC for an Openvario-Shell?

Clarifications here would be greatly appreciated. Looking forward to it.

Thank you.
Cheers!
