packers: Add support for deb packages #335

Closed manut closed 2 years ago

manut commented 2 years ago

For example initrd images might be used as input as build-dependency of a kernel package. Therefore implement a packer that is able to build simple debian packages.

I am not inclined to take this series because a deb package is really more than what is produced here. I do not see how this would benefit Elbe.

manut commented 2 years ago

I hoped to describe the use-case properly in the commit message. I want to build a initramfs with elbe. The output shall be a deb package, that i can use it as a build-dependency in a kernel package. Is there another way in elbe to build a system with a custom elbe-based-initrd?

bgermann commented 2 years ago

I get that. But that is not a complete Debian package as specified by the Debian Policy. No source package, probably no copyright file ...

manut commented 2 years ago

Got it. Thanks for the clarification. If the argument is, that any debian package produced by elbe shall be following the Debian policy, we shall also overthink: https://github.com/Linutronix/elbe/blob/392d9ad148120283995bdba38b778059cb591e4f/elbepack/commands/toolchainextract.py#L60

What is the recommended way in elbe to use a custom initrd, eg. to use a overlayfs for /etc ?

bgermann commented 2 years ago

You create a debian package that makes use of the update-initramfs hooks and install it in the system.

manut commented 2 years ago

This will be a bigger rework of the bootup, since currently the initrd is compiled in the kernel. I tried to avoid this in the first step. It will also increase the RFS size a bit, but probably this could be fixed in finetuning.
