'guix gc' as user makes system unbootable.- I had executed 'guix gc' and then 'guix package -i blender' and then 'guix package -u', all as user without running 'guix pull' recently (did it last week). When rebooting, current GrUB boot menu entry did not work. But previous versions (#1,#2,#3) worked at different levels. Below each menu entry I post my experience upon boting with it: menuentry "GNU with Linux-Libre 4.12.9 (beta)" Kernel panic menuentry "GNU with Linux-Libre 4.11.6 (beta) (#1, 2017-06-21 18:01)" No GUI. Lost keyboad configuration on tty's. Logged in as user. The output of 'sudo herd status' was 'error: connect: /var/run/shepherd/socket: No existe el fichero o el directorio'. menuentry "GNU with Linux-Libre 4.11.6 (beta) (#2, 2017-06-22 15:49)" Working GUI (no local keyboard as usual) and working Herd. Lost keyboad configuration on tty's. menuentry "GNU with Linux-Libre 4.11.6 (beta) (#3, 2017-06-30 13:36)" Working GUI (no local keyboard as usual) and working Herd. Lost keyboad configuration on tty's. menuentry "GNU with Linux-Libre 4.11.6 (beta) (#4, 2017-06-30 14:57)" Kernel panic menuentry "GNU with Linux-Libre 4.11.8 (beta) (#5, 2017-07-02 19:30)" Kernel panic menuentry "GNU with Linux-Libre 4.12.2 (beta) (#6, 2017-07-16 09:38)" Kernel panic menuentry "GNU with Linux-Libre 4.12.9 (beta) (#7, 2017-08-31 00:10)" Kernel panic menuentry "GNU with Linux-Libre 4.12.9 (beta) (#8, 2017-08-31 00:19)" Kernel panic menuentry "GNU with Linux-Libre 4.12.9 (beta) (#9, 2017-08-31 00:46)" Kernel panic menuentry "GNU with Linux-Libre 4.12.9 (beta) (#10, 2017-08-31 06:15)" Kernel panic menuentry "GNU with Linux-Libre 4.12.9 (beta) (#11, 2017-09-02 15:48)" Kernel panic This situation has happened before and has, as in this time, made my installation unbootable. But I did not notice that it was because of 'guix gc', until now. Is it normal that a user can affect the boot process for the whole operating system?
