What is the reasoning behind this method? Names are not supposed to contain slashes apart from the initial one, so this cuts into the supported length. If slashes were to be permitted, this would create a possible conflict where part of the name is the same as the path of a newly created jail. The standard way would be to provide an entirely separate namespace, if requested, and keep things the same otherwise. -- Mateusz Guzik <mjguzik gmail.com> _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
