Is there any way to check if a Bun installation was done through the official script

Hi, the Bum community!

I am a maintainer of Topgrade, a tool that is used to update everything.

Recently I encountered this issue, after discussion, I would like to only invoke the update procedure for Bun iff it is installed through the official script. Currently, I determine this by comparing if the Bun binary path is a descendant of the bun_install_path, from the install script, bun_install_path can be set via environment variable BUN_INSTALL, and if not set, defaults to ~/.bun.

The problem with this approach is that the environment variable BUN_INSTALL is not necessary after installation, it is only used during the installation.

I would like to know if there is any reliable way to check if an installation is done through the official script.

I would like this too, as I maintain different linux machines and it'd be nice to have a way to detect this. It will help for any automated installer/updater scripts and tools, including topgrade. Using this in ansible is another example.
