* Resynchronise with Debian. Remaining changes: - debian/control, debian/local/common-session{,md5sums}: use libpam-foreground for session management. - debian/rules: install unix_chkpwd setgid shadow instead of setuid root. The nis package handles overriding this as necessary. - debian/libpam-modules.postinst: Add PATH to /etc/environment if it's not present there or in /etc/security/pam_env.conf. - debian/patches-applied/ubuntu-fix_standard_types: Use standard u_int8_t type rather than __u8. - debian/patches-applied/ubuntu-rlimit_nice_correction: Explicitly initialise RLIMIT_NICE rather than relying on the kernel limits. Bound RLIMIT_NICE from below as well as from above. Fix off-by-one error when converting RLIMIT_NICE to the range of values used by the kernel. (Originally patch 101; converted to quilt.) - debian/patches-applied/ubuntu-user_defined_environment: Look at ~/.pam_environment too, with the same format as /etc/security/pam_env.conf. (Originally patch 100; converted to quilt.) - debian/patches-applied/ubuntu-regression_fix_securetty: securetty's earlier behavior would correctly prompt for password on bad usernames (LP: #139075). - Build using db4.5 instead of db4.6. - debian/libpam0g.postinst: only ask questions during update-manager when there are non-default services running (LP: #141309). * debian/libpam0g.postinst: don't display a debconf warning about display managers that need restarting when update-manager is running, instead signal to update-notifier if a reboot is required.
