Is it my imagination, or is Fedora Linux (and probably other distros too) releasing new Linux kernels at an increasing rate? I have a little shell script named cron_uptime which I run with cron every morning before I get up. It checks to see if the PC was rebooted in the past day. If not, it deletes the last line from my uptime log. In either case, it then puts the date and uptime at the end of the log. I used to boast that I only reboot my PC about every two months. But on closer examination, that's not been true the past few years. In 2010 I rebooted 19 times. In 2011 I rebooted 20 times. But this year is only 31% through, but I've already booted my PC 18 times (counting this morning, which hasn't been logged yet)! Two or three of those were due to a failed power supply, but I know I've already upgraded the kernel a number of times this year--which is the main reason I reboot. Is the pace of Linux kernel development accelerating?
