Hey Guix, In Guix System the system log files (/var/log/messages, /var/log/debug, etc.) are world readable by default. Since `dmesg' was restricted to privileged users a while ago [0] it seems reasonable to make these files readable by privileged users only as well.
What do others think? Regards, Diego [0]: https://git.savannah.gnu.org/cgit/guix.git/commit/?id=24446ce299943efe3dfded6c9dd0cf9421d8da04
