+Subject: [PATCH] Shellscript stops before completing
+
+Commit 8fb94d7 reworks the way shell script are called, redirecting
+stdout and stderr to SWUpdate. A shell script runs then in a child
+process. Under some circumstances, SWUpdate closes the forked process
+before the child process completes.
+
+Be sure that the child process has terminated before to go on.
