Interesting use case. But also a use case for which initramfs-tools probably very simply was never intended. I agree that in this case you probably want to either - have a very generic initrd that supports anything (Debian default) [1] or - provide a list of modules to include in the initrd based on knowing the hardware you want to support (e.g. using /etc/initramfs-tools/modules) and prevent including anything based on the host system. I've never really done that so I don't know if initramfs-tools has any features to support that. > If only there were a switch to prohibit ever looking at the > current machine's configuration when generating the initramfs...

It's obviously hard to comment on something like this without more details (which would be off-topic for this list). [1] Could still leave you with problems if the clients use something fancy for the root fs that uses info copied from /etc. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
