# Bug#17786581:SERVER WRITES INTO WORLD-WRITEABLE FILE EVEN AFTER WARNING ABOUT
# IT.
#
# Problem:
# ========
# UUID exists in a file named "auto.cnf", make this auto.cnf  file as world
# writable. The server starts, and it sees the auto.cnf is world writable and
# writes a following warning:
#
# Warning: World-writable con-fig file './auto.cnf' is ignored
#
# A new UUID is generated and the new UUID is once again  written to the same
# world writable file which is not safe.
#
# Test:
# =====
# During the execution of the script change file permissions of 'auto.cnf' to
# 777. Restart the server and check that the newly generated 'auto.cnf' file
# has valid 660 file permissions.
