Unitful missing from dependency list

[btmit]

Having Unitful as a hidden dependency breaks sysimg creation as soon as you move that sysimg. It appears to be looking for an absolute path at runtime.

Note this was built in Docker (hence root user name) and moved to another system where it is errors.

[mkitti]

It's an optional dependency. Is Unitful loaded in the environment?

[btmit]

No, it doesn't appear to be.

Package native code caching in Julia 1.9 should decrease the need to build a system image.

We should be able to remove the Requires.jl based mechanism when package extensions land which might also be Julia 1.9.

For pre-Julia 1.9, I think this might be a Requires.jl issue.
