Dear Stephane
Yes I understad now.
Do you think it would be good to create a mechanism to "detach" the container
from profile with a command. this way the container will preserve its function
even after the profile was changed. (apply all profiles to the container itself
and remove dependence on the profile)
Or maybe to add functionality to make a profile "read-only"? so that container
function can be preserved
Thank you very much for your kind help

Bug description:
I am trying to create a container without network interface.
during lxd init I selected not to create a bridge (and it was not created)
so
lxc init ubuntu:16.04/amd64 gerecon --profile default
lxc config device remove gerecon eth0
Device eth0 removed from gerecon
lxc config device remove gerecon eth0
Device eth0 removed from gerecon
already seems strange as the second call to remove eth0 claims that it was
happy to remove it
after the first call was successfull
if I try to start the container I get this:
lxc start gerecon
error: Error calling 'lxd forkstart gerecon /var/lib/lxd/containers
/var/log/lxd/gerecon/lxc.conf': err='exit status 1'
Try `lxc info --show-log gerecon` for more info
relevant piece of lxc info is:
lxc 20160811150615.590 ERROR lxc_conf -

conf.c:run_script_argv:367 - Executing script '/usr/bin/lxd callhook
/var/lib/lxd 15 stop' for container 'gerecon', config section 'lxc'
as you see, it is trying to connect to the bridge which does not exist using
network interface which should not exist in the container
lxc config show gerecon has this (reference to eth0 which should have
been removed)
profiles:
- default
config:
volatile.base_image:
199e9a37b6aa19a258b89fbbbcf99abb2e00d2b833b00db444da92f202d06ac5
volatile.eth0.hwaddr: 00:16:3e:bd:70:90
out of curiosity I did this
lxc config device set gerecon eth0 nictype bridged
error: The device doesn't exist
Am I doing something wrong or this is a bug ?
thank you very much for your help
