ostree-prepare-root is growing the same gpt-auto workaround for composefs roots (creating the /run/systemd/volatile-root symlink so systemd's blockdev_get_root() can resolve the backing device, see systemd/systemd#35017), proposed in ostreedev/ostree#3608. It runs before bootc-root-setup.service, so once that lands the symlink already exists by the time gpt_workaround() runs, and the unconditional symlink() call makes the service fail. Both creators point the symlink at the /dev/block/MAJ:MIN alias of the same physical root device, so simply ignore EEXIST, matching how ensure_dir() handles already-existing directories.

There was a problem hiding this comment.
Thanks!
(That said, not related to your PR but I think what we really want to do is actually add the overlayfs API to query backing layers)
