>> So /home/dev_1 (not $HOME; see error message) 

No, I was confused as well, sorry.

In the back of my mind was another user reporting they used some 
FUSE-based encryption of $HOME, and I thought you might be using 
that.  This tainted my thinking.

I have no other idea what could be happening.  What I ‘reproduced’ 
in my previous mail is probably not what is happening to you, even 
if the error messages are the same.

But it is definitely something related to your installation:

> guix shell --container coreutils -- echo Elmo

should, of course, always work.

Does this system have ‘uncommon’ kernel restrictions in place, 
like SELinux or other hardening?  Is there anything printed in 
dmesg when the container fails to start?

Kind regards,
