In sh, string comparison for equality is "=", not "==". Bash accepts either operator but suggests to use "=" for posix conformance. Our /bin/sh is currently busybox, which accepts "==" like bash, but if you use ash or dash it fails: $ CONFIG_FOO=y $ if [ "$CONFIG_FOO" = "y" ]; then echo ok; fi ok $ if [ "$CONFIG_FOO" == "y" ]; then echo ok; fi dash: 3: [: y: unexpected operator Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
