The option was initially named TARGET_ROOTFS_LN_VAR_TMP, and the check was correct. When renaming the option to something more suitable, the check was changed to check for n, but when an option is not set, it's not n but empty. This results in the check always evaluating to false. Fix the check by checking for y with ifneq. Fixes: 57807f50ded6 ("base-files: add option to make /var persistent") Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
