Hi,
Jail name is not jail's hostname, you can have jail1
with hostname machine.example.org
, change hostname without renaming the jail (even without access to host, this may be another discussion)
That said, I have to check what is done when changing hostname with iocage set
, it may lack /etc/rc.conf part...
That would not make sense in the cases of an empty or a Linux jail though.
Should rename be consistent with create new jail? My use case is create jail with -B -c 5 -n tmp to create 5 base jails named tmp_{1..5} for spare as create jail take minutes to complete. When I really use a jail ,I will rename it to some meaningfull name such as nginx. But it is annoy when I should edit the config.json and rc.conf and restart jail.
Historically, jail's 'name' were UUID's (hence the host_hostuuid field), and still are if you don't name them explicitely. Jail's hostname is initialized from that, but not enforced by default (allow_set_hostname defaults to 1).
Link beetween hostname and jail name(uuid) is not bijective, hostname only defaults to uuid if not explicitely given: I think we can't change hostname if not explicitely asked for (with iocage set host_hostname=…
)
Make sure to follow and check these boxes before submitting an issue! Thank you.
iocage --version
master
if using a stable release.iocage -v Version 1.2
iocage rename tmp_3 tmp3 Jail: tmp_3 renamed to tmp3
iocage console tmp3 root@tmp-3:~ # hostname tmp-3-----here and /etc/rc.conf should change to tmp3?
cat /zroot/iocage/jails/tmp3/config.json { "basejail": 1, "cloned_release": "13.3-RELEASE", "host_hostname": "tmp-3",------here,should be tmp3? "host_hostuuid": "tmp3", "jail_zfs_dataset": "iocage/jails/tmp3/data", "last_started": "2024-09-08 05:58:27", "release": "13.3-RELEASE-p4" }
should iocage change the config.json and the hostname of jail?
