The unveil man page is perfectly correct and it is not hard to test it's behaviour.
I just wonder if it may aid unveil adoption in languages other than C, if it explicitly mentioned that exec is not required on a dir to allow reading the files within, e.g. if the dev is more used to filesystem permissions than OS functions? Perhaps a FAQ on unveil is intended instead, time permitting? Perhaps a link to the following paper or whichever best demonstrates usage, could be added to the faq for now? https://lteo.net/assets/pdf/lteo-openbsd-carolinacon15-20190427.pdf Trying to help provide differing perspectives and not just create work for people. Feel free to ignore me, obviously.
