[bug]: cp without source file check

[ethnh]

What happened?

sorry I understand this is a less than supported OS , but with default settings I am getting error on zinit:
cp: cannot stat '/nix/store/p8aykjsfiz14y4cnhjdwim5zz2kxa1p3-zinit-3.13.1/share/zinit/doc/zinit.1': No such file or directory
Related to #418

I am going to submit a PR that adds a check for the source file before it cp's just to resolve this error for me. I understand impact is low but I will write it so that no other users are affected negatively.
Is it fine? 🙏 🙇
