nice hint from the Season 3, episode 1 Tuxradar podcast – logger. You can add notes to the system log, even as a user. So:
$ logger added a new kernel $ sudo tail /var/log/messages.log Feb 24 21:45:41 localhost kernel: usb 3-2.1: new full speed USB device using uhci_hcd and address 46 Feb 24 21:45:41 localhost kernel: hub 3-2.1:1.0: USB hub found Feb 24 21:45:41 localhost kernel: hub 3-2.1:1.0: 4 ports detected Feb 24 21:45:42 localhost kernel: usb 3-2.1.1: new full speed USB device using uhci_hcd and address 47 Feb 24 21:55:20 localhost -- MARK -- Feb 24 22:06:12 localhost jdarnold: added a new kernel
That’s pretty cool. As I showed, I just added a note that I have a new kernel now, so if there’s any question about compatibility, I’ll know!
