Bug ID: 274568
Summary: rc.conf(5): Empty "jail_list" does not start jails
defined in "/etc/jail.conf.d"
Product: Base System
Version: 13.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: conf
Assignee: bugs@FreeBSD.org
Reporter: stephen.j.fox.jr@gmail.com
According to the manual page for rc.conf(5), an empty "jail_list" variable
should result in all jails being started on boot or with "service jail start":
jail_list (str) A space-delimited list of jail names. When left empty,
all of the jail(8) instances defined in the configuration
file are started. The names specified in this list control
the jail startup order. jail(8) instances missing from
jail_list must be started manually. Note that a jail's
depend parameter in the configuration file may override this
list.
In FreeBSD 13.2-RELEASE, "service jail start" with an empty jail_list results
in the following error message with an exit status of 0:
"/etc/jail.conf: No such file or directory"
The following shell output demonstrates this issue:
```
# uname -a
FreeBSD freebsd-sketch 13.2-RELEASE-p3 FreeBSD 13.2-RELEASE-p3 GENERIC amd64
# file /etc/jail.conf.d/foo.conf
/etc/jail.conf.d/foo.conf: ASCII text
# grep '^jail_list' /etc/rc.conf
jail_list=""
root@freebsd-sketch:~ # service jail start
Starting jails:jail: /etc/jail.conf: No such file or directory
.
# echo $?
0
# jls
JID IP Address Hostname Path
# # Edit rc.conf to manually specify the "foo" jail.
# grep '^jail_list' /etc/rc.conf
jail_list="foo"
# service jail start
Starting jails: foo.
# jls
JID IP Address Hostname Path
