Hello

I am using dual copy approach with on a Debian based system. Grub2 is used as bootloader. In the preinstall and postinstall scripts I want to see what happened in the grub environment block. I noticed that during the update the bootloader variable ustate is set to 7. But when the update is done, then it can be seen that ustate is set to 1 normally because the update was installed successfully.

My question is why ustate is set to 7 during the update?

If you just look into the sources, it is self explained:
