Hi! There's a debian-specific patch in busybox since 2017 which adds ability to lift variable name filtering rules for d-i. A comment in there says:
This is not a long term fix for this problem: a different approach is
needed to parse the values from the kernel command-line, but we don't
want to be responsible for holding up the debian-installer alpha
release any longer than it has already.
Is it still needed in 2024?
Thanks,
