Subject: using guix to install packages from inside a container that runs on
 foreign distro breaks guix and the foreign distro
Date: Fri, 01 Jan 2021 18:02:01 +0100

Hi!

using guix to install packages from inside a container that runs on 
foreign distro breaks guix and the foreign distro, see below:


Steps to reproduce:

The below system was instantiated witg guix system container 
this_file.scm --network

upon starting it with sudo /gnu/store/asdfasdfasdf-run-container


and connecting to it with

sudo guix container exec 8625 /run/current-system/profile/bin/bash 
--login
[sudo] password for david:

As you can see, guix is now broken on both the host and guest system.

By the way, WARNING: when i say breaking the foreign distro, I mean 
breaking not only guix - everytime I tried this I have been unable to 
login to the system again after a logout. I have tried this on Debian 
GNU/Linux 9 inside a VM which is snapshotted so I can restore it.

Best regards,
David

Hi David,

Looks like this bug report fell through the cracks of the turn of year…

It looks as though the store item for Guix or Guile used on the host had
been suddenly wiped, even though we don’t see any GC activity or
similar.

Were you able to better see what was broken?  Is it that store items
were removed?  Are there issues with non-Guix files?  It would be great
if you could gather more details as to what’s wrong.  I’ll also see if I
can try that in a VM.

Thanks,
Ludo’.

No, unfortunately I couldn't find any reason. I repeated it a few times 
with the same results but I no longer have access to the VM I tested 
this on so I can't help with more details, sorry :/

If it does not happen when you try it (if you do), I would be glad to 
hear about so I can call this a fluke and attribute the bug to special 
unknown circumstances with the particular host system I used.


Best regards,
David
