title: Is a POSIX_NAME_MAX value of only 14 as expected in Mac OS?
body: <p>I'm working on a filename convention, and I'm using the POSIX Portable File Name Character Set (e.g. <a href="https://www.ibm.com/docs/en/zos/2.4.0?topic=locales-posix-portable-file-name-character-set" rel="nofollow noreferrer">here</a>) as a starting point. I thought I'd run a quick check using 'pathchk -p' (I'm on macOS 11.3, Big Sur) to see how things stand to begin with and I was surprised to find a whole bunch of my files failed the check.</p>
  <p>In almost all cases, the reason given was that the length of one or more of the filename components exceeded what's specified in POSIX_NAME_MAX. However, the error message said that limit was only 14 characters, which struck me as very short. I'd have expected at least 255. But, sure enough, 'getconf' confirmed that POSIX_NAME_MAX is indeed 14.</p>
  <p>Is a value of 14 really to be expected for POSIX_NAME_MAX?</p>
