If the root has a password, and we boot the system up to make it enter rescue mode, the root cannot login. This is because in rescue mode, `sulogin' is invoked as the login manager. How to reproduce: 1. Add in local.conf: INHERIT += "extrausers" EXTRA_USERS_PARAMS = "usermod -P 'root' root; \ useradd -P 'test' test;" 2. bitbake core-image-minimal 3. runqemu qemux86 nographic bootparams="-s" P.S. Both sysvinit and systemd have the this problem. //Chen Qi

This leads to the problem when booting into rescue mode in an image with shadow installed but not sulogin from util-linux. To fix this problem, we add 'util-linux-sulogin' to RDEPENDS of shadow. This runtime dependency is specific to OE, because we have to ensure that sulogin can work correctly and sulogin from busybox cannot because FEATURE_SHADOWPASSWORDS is not enabled by default. And we cannot enable it by default for busybox, because that would lead to utilities in busybox to assume the existence of /etc/shadow which is not always true in OE.
