I think it is /proc/sys/kernel/unprivileged_userns_clone, but I don't know what the contents are exactly. 0 when off, 1 when on? Can someone on Debian confirm? If we can get the test suite passing, I'd like to extract these user namespace presence tests to a procedure that 'guix environment' can use to give the user an informative error message in these cases. - Dave
