This script from man hdiutil no longer works:
devnode=$(hdiutil attach -nomount ram://102400)
newfs_hfs “$devnode”
mount -t hfs “$devnode” /path/to/ramdisk
because $devnode contains spaces and tabs!!
$ hdiutil attach -nomount ram://1 | xxd

# remember to clean up afterwards
$ hdiutil detach /dev/disk4
Please properly quote your variables in CI test scripts to catch such regression. It could pass because unquoted expansion of $devnode undergoes word splitting after the variable is substituted, removing the trailing whitespaces.
