+# FS QA Test No. 261
+#
+# This test exercises an issue in libxcmd where a problem with any
+# mount point or project quota directory causes the program to exit
+# complete. The effect of this is that one cannot operate on any
+# directory, even if the problem directory is completely unrelated
+# to the directory one wants to operate on.
