Hello Guix, During 'guix system reconfigure' I got a kernel panic. Getting it quite often while 'guix system reconfigure' at Linux magnolia 4.13.4-gnu #1 SMP 1 x86_64 GNU/Linux. But it's not a subject of current report. After reboot I tried another attempt to make a 'guix system reconfigure', but because of /etc/group.lock and /etc/passwd.lock operating-system groups and users fields didn't applied. I tried to get a creation of adbusers group and add my user to it, but because of those files I cannot do it, until manually removed them. So, do we need to check if *.lock files are exist and remove them at the start of 'guix system reconfigure' OR abort reconfigure and creation of Grub boot entry OR something else? Thanks, Oleg.
