Under FreeBSD, errno.2 is only a link to intro.2. This link was there in libc/sys/Makefile.inc rev.1.1. More than half of intro.2 is about error numbers. I expected to find error numbers described in strerror.3 or perror.3. perror.3 is only a link to sterror.3 (so is sys_errlist.3, which is probably the right place for documenting the list). strerror.3 refers to intro.2 but not errno.2. errno.2 is referred to mainly in au_token(3) and its 46 links. apropos(1) does an especially poor job for errno since it gets spammed more than usual by links, and errno isn't a function. It doesn't find errno(2), intro(2) or strerror(2), but it finds au_bsm_to_errno(3) and many other functions with errno in their name, and then gets spammed by links to these; it finds pcap_strerror(3) due to errno in its description, and it finds perl's Errno(3).
