ChangeLog

+2008-06-02  Per Cederqvist  <ceder@shafan.lysator.liu.se>
+
+	Facilitate moving stuff between partitions.
+	* Makefile (install): Added lysrdiff-clone-tasks and
+	lysrdiff-move-many.
+	* lysrdiff-clone-tasks: New script.
+	* lysrdiff-move-many: New script.
+
+	Fix quota1.
+	* fetch-backup-work: quota1 comes from /export/users, not
+	/export/home.
+
+	Fix reporting of warnings.
+	* lysrdiff-set-status.py: The --warn option was misnamed --warning
+	in this script, but not in the rest of the system.
+
+	Get rid of false warnings, and be careful with the clones.
+	* backup-one-task: Don't mix output from "rdiff-backup --clean"
+	and the regular "rdiff-backup" job.  Only clone good backups.
