The SPARC64 netboot image from 20070724 (found at http://mirror.ovh.net/gentoo-distfiles/experimental/sparc/tftpboot/sparc64/) provides shadow-utils without PAM support, making it impossible to 'su -'. In particular, if the system is installed without updating this package and including PAM support, one can be locked out of the root account when logging in as an ordinary user. Reproducible: Always Steps to Reproduce: 1. Install a SPARC64 system using the provided netboot image. 2. 3. Actual Results: Unable to 'su -'. Expected Results: Should be able to 'su -' to any user, including root.
Uhh, what? The netboot image uses busybox and automatically logs you in as root. There is no shadow package.
My mistake! It's possible I should've filed this as a bug in the stage3 tarball. I remember that once I installed the tarball, built the kernel, and rebooted, I couldn't 'su -' to anything.
