Custom init script?

[khuongduybui]

I am trying to build a custom distro where the base image does not contain "useradd".
How do I provide a custom init script that install packages like shadow-utils, sudo, passwd, util-linux-user, etc.?

You can't use any init script now,sorry...
But you can use custom .tar.gz package.

If I launch the WSL instance with the provided base rootfs.tar.gz, then install whatever I need, and then use the launcher's backup functionality to create my custom tar.gz, can I use it as the source rootfs.tar.gz on another machine?

[yuk7]

Yes,you can.
You can use backup tar.gz for another machines.
