I've added sysctl debug.bootverbose=1 to /etc/sysctl.conf and rebooted. The reboot completed without complaints about errt, but as it came up multiuser the console reported: sysctl: unknown oid 'sysctl debug.bootverbose' at line 11 However, if I type sysctl debug.bootverbose=1 while logged in as root I see root@pelorus:~ # sysctl debug.bootverbose=1 debug.bootverbose: 0 -> 1 root@pelorus:~ # So, for some reason the command has to be entered interactively, at least for now. Rebooting with shutdown -r reported swap device removal. The errt complaint remained absent. There's something odd about sysctl debug.bootverbose. For example: root@pelorus:~ # sysctl -a | grep -i bootverbose <118>sysctl: unknown oid 'sysctl debug.bootverbose' at line 11 debug.bootverbose: 0 root@pelorus:~ # sysctl debug.bootverbose debug.bootverbose: 0 root@pelorus:~ # sysctl debug.bootverbose=1 debug.bootverbose: 0 -> 1 root@pelorus:~ # Am I committing some invisible (to me) typo?
