Subject: [RFC PATCH v3 00/10] Add support for dracut
Date: Mon, 6 Oct 2025 20:31:02 +0200 [thread overview]
Message-ID: <20251006183214.1593195-1-Quirin.Gylstorff@siemens.com> (raw)
From: Quirin Gylstorff <quirin.gylstorff@siemens.com>
Debian intends to change the default initrd generator from
initramfs-tools to dracut[1],[2].
This is a first draft to support multiple initrd generator in
ISAR. I tested it with bookworm and trixie.
Currently missing is the possibility to generate custom dracut initrd.
This will be added in a future revision of this patch set.
