Re: [lxc-users] Trouble with automounting /dev/shm

[Stéphane Graber]

Yes, that works fine.

You can set it with: printf line1\nline2 | lxc config set CONTAINER raw.lxc -

Or through a multi-line yaml entry and "lxc config edit"

You can't. As far as LXD is concerned raw.lxc is a single string
configuration key, whichever profile or container local config contains
it last will win.

Re: [lxc-users] Trouble with automounting /dev/shm

[Pavol Cupka]

Going to answer my own question.

It was due to another profile being applied to the container also with
raw.lxc option so it hijacked the option and the option with dev/shm
never got applied.

So works without the second profile.

Subquestion: How to add another raw.lxc line to a second profile
without canceling the first one?

Thanks
