Hello Ludovic, apologies for not adding logs before. It's hard to do when I do guix commands from Xterm and not from Emacs. Emacs *shell* or *compilation* buffers will eat all memory if they get too much text. Probably need to redirect STDOUT STDERR in file when Xterm do guix. I heard Guix folks work on implementing tiny log output to console and redirect everything else to a log file. This will be my life saver. ludo@gnu.org (Ludovic Courtès) writes: > Hello, > > Oleg Pykhalov skribis: > >> During 'guix system reconfigure' I got a kernel panic. > > Can you show the exact command and its output? Sorry, as I said this is not a topic and I don't want to do it again and I caution to make it on my current system. I will setup a specific Guix VM for this, where I could make a 'system reconfigure'. Then I'll create a new bug report with full log. Neverless I'll leave a how-to reproduce it below for at least for myself TODO list. The problem =========== The bigger problem from my view are files like /etc/group.lock and /etc/passwd.lock. For example: sudo touch /etc/group.lock /etc/config.scm (operating-system ;; … (groups (cons (user-group (name "test")) %base-groups))) reconfigure log
