Changing the order of checks in entrypoint 10

[aqeelat]

Wouldn't flipping these lines make more sense?
If ipv6 is enabled then we wouldn't need to check if the file is writable. The exit message will be more informative, instead of sending the user in a wild hunt.

docker-nginx/entrypoint/10-listen-on-ipv6-by-default.sh

Lines 26 to 30 in 6a4c0cb

	# check if the file can be modified, e.g. not on a r/o filesystem
	touch /$DEFAULT_CONF_FILE 2>/dev/null || { entrypoint_log "$ME: info: can not modify /$DEFAULT_CONF_FILE (read-only file system?)"; exit 0; }
	# check if the file is already modified, e.g. on a container restart
	grep -q "listen \[::]\:80;" /$DEFAULT_CONF_FILE && { entrypoint_log "$ME: info: IPv6 listen already enabled"; exit 0; }
