--- Comment #28 from Konstantin Belousov <k...@freebsd.org> --- The failing op is clear: 1727 jail CALL jail_attach(0x2) 1727 jail RET jail_attach -1 errno 1 Operation not permitted but why is it failing with EPERM is not. First question, do you have any mac modules configured and loaded? Second, could you try to install HEAD kernel (just kernel, not world) temporary and see if the funny failure mode persist? -- You are receiving this mail because: You are the assignee for the bug.
