How can different versions of julia in juliaup share a same `startup.jl` file?

For example, I have installed julia v1.11.2 and v1.10.7 in juliaup and they both appears in the `JULIAUP_DEPOT_PATH`, but the `startup.jl` files are located in their own directories. I want them share a same `startup.jl` file, what should I do?

In unix, linux and MacOS

You can use symbolic link to point to a single startup.jl file.

You should really only ever modify/use `~/.julia/config/startup.jl`, and that will be used by all Julia versions that use this depot.

The `startup.jl` files that are inside the `~/.julia/juliaup` folders shouldn’t be edited by users (I kind of wish they didn’t even exist in the distributions of Julia).

Thanks for your reply, @davidanthoff ! 🤝

BTW, may I ask you the necessary configuration for the installation of portable juliaup and julia? After unziping the juliaup package to a place, for example, a USB drive `F:\`, I need to add `F:\juliaup` to the `Path` environment variable and at the same time to create a new environment variable named `JULIAUP_DEPOT_PATH` and set its value to point to someplace in `F:\`. Am I right? Is this all I need to do? How should I change the default path of the folder `~\.julia` to the USB drive? Do I have to repeat these configurations every time I insert the USB drive into a new computer? I wonder whether there is any method that we can configure these within the portable juliaup and julia?

Waiting for your attention and thank you in advance!
