So you don't have any shared memory in the container then.

Probably a good thing though, at least in respect of security.

# df -h

On the last line I see /run/shm, but no /dev/shm

Looks like vultr isn't exposing shared memory in it's containers but that's just an uninformed guess on my behalf.

Can you see /dev/shm in the output of df -h?

Devuan lets me work my way up from scratch

I hear you on that. It is my preferred way to build, not desktop install and then removing stuff.

Question, on my desktop, this ps_mem.py works fine. But on another system I get this error. Any ideas on what is missing?

$ sudo ps_mem.py
File "/usr/local/sbin/ps_mem.py", line 448
"%s: Shared memory is not reporte
^
SyntaxError: EOL while scanning string literal

The difference between the two systems is that the one that works is a desktop install. The other is a virtual machine, devuan (ascii) on vultr.

Python is installed:

python is already the newest version (2.7.13-2).

Are you sure you're running devuan?

Oh yes, that's Devuan — I used the netinstall ASCII image then upgraded to beowulf and installed my simple-desktop package and switched to OpenRC.

It's running under 64-bit QEMU/KVM with 4GiB assigned and it runs very well indeed.

antiX is awesome but I would have to spend ages gutting it like a fish to get the desktop I want but Devuan lets me work my way up from scratch, which is much quicker and simpler

Yes, I tried that before and after allowing javascript. It didn't work. I can never see twitter, either. Just a big blue bird. Maybe my computer is trying to protect me from what's there.
