Linux Easter Egg - Hidden Dates in the Linux Kernel
In order to prevent the reboot() system call being
called inadvertently, you must pass it a pair of magic values in the first two parameters. The first magic value is 0xfee1dead. The second magic value
is one of:
$ grep LINUX_REBOOT_MAGIC include/linux/*.h
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC1 0xfee1dead
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2 672274793
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2A 85072278
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2B 369367448
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2C 537993216
These are dates of significance to Linus; hint
you can use perl to convert them into dates:
$ perl -e 'print localtime(672274793). "\n";'
Sun Apr 21 18:59:53 1991
This is the date that Linus first started writing Linux. The significance of other dates is left as an exercise for the reader ;-)
