[Message part 3 (text/plain, inline)]

In the new guix `guix environment --container` is borken.

The reason lies in the 8bc5ca5160db3d82bd5b6b2b7ed80c96f42bd33e of the master branch:



It checks if the file exists and then returns a boolean




None of my 3 Guix System machines have this file but they can still run unprivileged containers.

Please fix it,

thanks very much

...because this only works on the Debian kernel.

We need to find a more robust test for user namespaces, but for now I
reverted the commit.

Closing!  Thanks for the report luhux.  :-)
