Jamie Gritton 5cf7054917 jail: only chdir to user's home directory when user is specified ... jail(8) with the "exec.clean" parameter not only cleans the enviromnent variables before running commands, but also changes to the user's home directory. While this makes sense when auser is specified (via one of the exec.*_user parameters), it leads to all commands being run in the jail's /root directory even in the absence of an explicitly specified user. This can lead to problems when e.g. rc scripts are run from that non-world-readable directory, and run counter to expectations that jail startup is analogous to system startup. Restrict this behvaiour to only users exlicitly specified, either via the command line or jail parameters, but not the implicit root user. While this changes long-stand practice, it's the more intuitive action. jexec(8) has the same problem, and the same fix.
