I do not know about ezjail, I set up jails "by the book", i.e. by just
following FreeBSD HandBook (this way I feel in control of everything...
and it doesn't take much effort). Anyway, here is what one of my jails
reports:
root@maia:/ # uname -n
maia.uchicago.edu
which _is_ FQDN. I'm sure, this comes from "host.hostname" line in jail
configuration. The following is the portion of /etc/jail.conf (on host
sytem) defining that particular jail:
maia {
host.hostname = "maia.uchicago.edu";
ip4.addr = 128.135.20.83;
devfs_ruleset=7; // integer number of devfsrules_jail_bpf ruleset
// in /etc/devfs.rules
persist; // Required because there are no processes
exec.start = "/etc/rc.d/cron start; /etc/rc.d/syslogd start;
/usr/local/etc/rc.d/clamav-freshclam start;
/usr/local/etc/rc.d/clamav-clamd start; /usr/local/etc/rc.d/sa-spamd
start; /usr/local/etc/rc.d/maiad start; /usr/local/etc/rc.d/apache24 start";
exec.stop = "/usr/local/etc/rc.d/clamav-freshclam stop;
/usr/local/etc/rc.d/clamav-clamd stop; /usr/local/etc/rc.d/sa-spamd
stop; /usr/local/etc/rc.d/maiad stop; /usr/local/etc/rc.d/apache24 stop;
/etc/rc.d/syslogd stop; /bin/sh /etc/rc.shutdown";
}
The very first line in configuration must be the one defining it.
(I'm still attempting to set up /usr/ports/security/maia software - in
jail - which gives users ability to tweak their individual spam
settings, including white/black lists, hence the origin of hostname...
didn't succeed yet, though still making small progress steps every time
when I have chance to work on it...)
There may be something similar in ezjail configuration.
I hope, this helps.
