Author: mizhka Date: Fri Sep 20 19:45:37 2019 New Revision: 352560 URL: https://svnweb.freebsd.org/changeset/base/352560 Log: MFC r352263: [jail] removal by jid doesn't trigger pre/post stop scripts This commit fixes bug: command "jail -r" didn't trigger pre/post stop commands (and others) defined in config file if jid is specified insted of name. Also it adds basic tests for usr.sbin/jail to avoid regression.
