How to include default initrd AND a custom one?

[septatrix]

Is it possible to use the default initrd and a custom one? The document seems to suggest that this is not possible. As soon as Initrds= is specified the default initrd is no longer build.

I am aware that one can use Include=mkosi-initrd in ones initrd configuration but that is not equivalent as stuff like kernel modules, image-id/-version, hostname etc. are no longer taken from the main config.

@septatrix Use InitrdInclude= to dump whatever extras you need into the default initrd.

What we want in the end are two initrds/UKIs so this would not work. One of them would just be the normal one and another would function as an installer.

What would also work is to generate two UKIs from the default initrd but one of them with rd.systemd.unit=installer.target or init=/installer.sh appended to the KernelCommandLine= but I am not aware of any way to do this either.

@septatrix Each UKI that mkosi generates gets the same initrds. The only thing that differs is the kernel modules. We do not support having different initrds for different UKIs
