+#!/bin/sh
+# Example script for automatically updating sbuild chroots
+#
+# Simply create a crontab /etc/cron.d/sbuild-update-all and specify the
+# schedule that you want to use. The behaviour of this script can be influenced
+# by the following evironment variables:
+#
+#   PATTERN     glob pattern to match the chroot config name against, in
+#               directory /etc/schroot/chroot.d/.
+#
+#               Default: *-sbuild
+#
+#   UPDATEARGS  The arguments with which sbuild-update will be invoked.
+#
+#               Default: --update --dist-upgrade --autoclean --autoremove
+#
+#   LOGFILE     Log file to write to. These files are not rotated, you must set
+#               this up yourself. See logrotate(8)
+#
+#               Default: /var/log/sbuild-update-all.log
+#
+# This script will refuse to run if another instance of it is running. In fact,
+# it will refuse to run if there is an active chroot session (regardless of
+# whether it is related to the matched patterns or not). Care for this must be
+# taken when scheduling cron jobs, as crontabs are processed sequentially (with
+# regards to variable assignment), but jobs are executed in parallel. 
+#
+# Examples
+# ========
+#
+# 1. Update all sbuild chroots four times a day (at 00:15/06:15/12:15/18:15):
+#
+#     15 */6 * * * root /usr/share/doc/sbuild/examples/sbuild-debian-developer-setup-update-all
+#
+# 2. Update all sid sbuild chroots daily, and all jessie sbuild chroots weekly,
+#    and log the latter to a separate file:
+#
+#     PATTERN = sid-*-sbuild
+#     @daily    root /usr/share/doc/sbuild/examples/sbuild-debian-developer-setup-update-all
+#
+#     PATTERN = jessie-*-sbuild
+#     LOGFILE = /var/log/wheezy-chroot-update.log
+#     @weekly   root /usr/share/doc/sbuild/examples/sbuild-debian-developer-setup-update-all
+#
+# The following will NOT work. Both of these jobs are executed at 00:15, so
+# the second one will refuse to run:
+#
+#     PATTERN = foo-*
+#     15 0  * * * root /usr/share/doc/sbuild/examples/sbuild-debian-developer-setup-update-all
+#
+#     PATTERN = bar-*
+#     15 0  * * * root /usr/share/doc/sbuild/examples/sbuild-debian-developer-setup-update-all
+
+
+# Output of sbuild-update invocations will be written to this file
+LOGFILE=${LOGFILE:-/var/log/sbuild-update-all.log}
+
+# Arguments passed to sbuild-update
+UPDATEARGS=${UPDATEARGS:-"--update --dist-upgrade --autoclean --autoremove"}
+
+# chroot config names are identified by this pattern
+PATTERN=${PATTERN:-*-sbuild-*}
+
+
+# Open logfile for output, make sure we're the only instance active
+exec 8>>$LOGFILE
+if ! flock -x -n 8
+then
+	echo "$0: another instance is already running"
+	exit 1
