From 3a4bd7ddefbf5b412a2b4031d491f5a50f1908cd Mon Sep 17 00:00:00 2001 From: Ricardo Salveti Date: Mon, 18 Aug 2025 21:56:05 -0300 Subject: [PATCH] initramfs-framework: mount /run and move to rootfs before switch_root Mount /run as tmpfs during early init and include it in the set of mounts moved to $ROOTFS_DIR prior to exec switch_root. Having /run available early lets initramfs modules stamp state that can later influence systemd service jobs, since systemd will reuse the mount point instead of creating a new one during boot. This is particularly useful with ostree, as it uses /run/ostree-booted as way to describe that the rootfs comes from an ostree deployment.
