Subject: [PATCH v2 3/6] vm: build GPT images
Date: Sun, 9 Oct 2022 11:40:33 +0000 [thread overview]
Message-ID: <20221009114036.463071-4-hi@alyssa.is> (raw)
In-Reply-To: <20221009114036.463071-1-hi@alyssa.is>
This will allow booting reliably from multiple disk images, without
relying on order or requiring udev in an initramfs. (The only
deterministic way of doing boot order on Linux without special
userspace support is to set "root" on the kernel command line to
either a GPT partition UUID or label.)
