From 0661997cea165e951e4e215e6aed41596d8b1d52 Mon Sep 17 00:00:00 2001 From: Navdeep Parhar Date: Thu, 19 Mar 2026 17:39:17 -0700 Subject: [PATCH] loader(8): embedded MD should be the most preferred currdev A loader built with MD_IMAGE_SIZE is almost always meant for use with its embedded image and should try that as currdev before anything else. Recent changes (d69fc3a9dc71, 784150fd2535) seem to have relaxed the ZFS code's search for a rootfs and exposed this problem.
