Configure SSH public key with LROS

I am trying to configure a public SSH key for Linerate. According to /etc/ssh/sshd_config it needs to be configured under /var/run/sshd_authorized_keys.d/ However I can't write files in that director...
lros
ssh

I'm not sure why, or how you are logged in as root, but if you 

ssh admin@hostname
, you are dropped at the 
LROS
prompt. If you then type 
bash
, you will be dropped into a bash shell as the admin user. You can then run commands using 
sudo
, which will give you permission to write to the file you need to write to: 
sudo vim /var/run/sshd_authorized_keys.d/admin
.

I just did this on a 2.6.1 installation and it works very nicely. I'm not sure whether the 

/var/run
directory will persist between reloads, though. I still need to test that. This comment makes me think that it might be possible to configure this through LROS, but I haven't been able to find a command or any other documentation:

 The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
 but this is overridden so installations will only check the LROS managed dir
AuthorizedKeysFile      /var/run/sshd_authorized_keys.d/%u
