Like all programs, init(8) may need to be ptrace(2)-attached, due to bugs or testing new changes; generally, allowing that would be very convenient when working with init(8)-related debuggings. Although I currently didn't have a need to debug the FreeBSD init(8), this report was a generic idea open for discuss. --=20 You are receiving this mail because: You are the assignee for the bug.=
