I noticed that a USER with an arbitrary ID is injected into /etc/passwd [1]
Is there a way to control the username that gets injected into /etc/passwd?

The reason I’m asking is that having user.name == user.id causes issues such as [2].
At the very least, it would be helpful to have a prefix for the injected username.

[1] #2022
[2] shadow-maint/shadow#1339
