* Merge from Debian unstable, remaining changes: - debian/libpam-modules.postinst: Add PATH to /etc/environment if it's not present there or in /etc/security/pam_env.conf. (should send to Debian). - debian/libpam0g.postinst: only ask questions during update-manager when there are non-default services running. - debian/patches-applied/series: Ubuntu patches are as below ... - debian/patches-applied/ubuntu-rlimit_nice_correction: Explicitly initialise RLIMIT_NICE rather than relying on the kernel limits. - Change Vcs-Bzr to point at the Ubuntu branch. - debian/patches-applied/pam_motd-legal-notice: display the contents of /etc/legal once, then set a flag in the user's homedir to prevent showing it again. - debian/update-motd.5, debian/libpam-modules.manpages: add a manpage for update-motd, with some best practices and notes of explanation. - debian/patches/update-motd-manpage-ref: add a reference in pam_motd(8) to update-motd(5)
