Hi Guix Development, I rely on the -C option below to compile ./pre-inst-env .
guix environment -C guix (I learned the technique through https://gitlab.com/pjotrp/guix-notes/blob/master/INSTALL.org - ./pre-inst-env just won't compile correctly unless I follow the instructions on the page) However, this feature has become unavailable after the commit 8bc5ca5160db... ~/co/guix (master)$ guix environment -C guix guix environment: error: cannot create container: unprivileged user cannot create user namespaces guix environment: error: please set /proc/sys/kernel/unprivileged_userns_clone to "1" The commit details are below: commit 8bc5ca5160db3d82bd5b6b2b7ed80c96f42bd33e Author: Paul Garlick <pgarl...@tourbillion-technology.com> Date: Thu Dec 3 16:00:18 2020 +0000 linux-container: Correct test for unprivileged user namespace support.
