Why is docker0 in sys-net here?

user@sys-net:~$ ip -s link show

Did you modify the template?

Only good reason I see is docker being installed in that template.

3

Hmm… oh man… thanks! Yeah, I’ve dabbled with Docker before. I need to set up Qubes OS from scratch again.

4

no, just remove and re-install the template. And stop modifying the original templates from Qubes OS, clone them and work with those.

5

Yeah, I’ll do that as soon as I have more hard drive space. That’s the main reason why I’m always fiddling around with TemplateVM.

6

Not sure what you’re doing but they shouldn’t take up that much space.

How much space do you have? I highly doubt its because of template VMs.

7

Every time a template is cloned, its “content” is also cloned.
In Qubes Manager, the disk usage is displayed under “Disk Usage.”
If I clone a 5GB template, the clone also uses 5GB.
If I create 10 clones, my templates alone will use 50GB.

Also I’d recommend to just use debian-13-minimal, no need to have this “everything installed” template for the VM that just runs one application (kuhbs does it like this, it always starts from scratch).

No:

11

Ok, fair port.

Then wait for kuhbs, it uses the debian minimal template and does all the management for you :wink:

But I miiiiiiight switch to kicksecure still, not sure yet. I very very much want to.

But yeah, fair, just use the -xfce templates, they do make everything simpler. Absolutely true.

Love adw’s post there btw.. Some quotable things for the website like the 80/20 thing..

@kuhbs I’ve posted a new entry here:
