2 * checkrestart:
3 - Do not complain about deleted files in /tmp, /var/run or /var/log
4 when seen as descriptors (Closes: #441529)
5 - Fix typo in checkrestart (Closes: #444473)
6 * network-test:
7 - Include patch provided by Federico Ceratto which adds command
8 line support, allows the setting of a verbosity level and makes
9 it possible to log to syslog based on that level. This patch
10 is useful if the script is run through init, cron or other
11 task-scheduling tool.
