When selecting shell, I have single-user mode on host sys= tem. This is with the default setting in /etc/ttys, where local console is considered secure. I tried pressing ctrl + \ constantly during rc.d execution but not during /etc/rc.d/jail script exectution, and this behaviour was NOT happening. It seems to be specific to the /etc/rc.d/jail script. Once I entered single-user mode, I saw all jails had started, even though t= he core dump and single-user mode happened while jail 2 out of 8 were being started. If I set local console to not be considered secure (i.e. require password to enter single-user mode), I am prompted for root password. This is definitely a bug, but considering it doesn't let you skip password = on insecure console I wouldn't consider it a security issue. Please let me know if any more details are required to solve this problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
