In the course of playing with the lfs, I managed to crash my machine.
Upon reboot, I got the following:
WARNING: clock time much less than file system time
WARNING: using file system time
WARNING: CHECK AND RESET THE DATE!
When I check the date, it says:
Dec 28 18:33:57 1965
That's amusing, as the epoch is 1970; overflow, anyone?
Anyway, I reset the time using date, but every time I reboot, the
kernel grabs the time from the filesystem. I read the problem thusly:
1) The kernel has insufficient sanity checking when it sets the date.
2) The time format shouldn't allow overflow, if that's what's really
3) When I use date to set the correct time, the filesystem time
should be set to the same value; otherwise, I'll have to reset the
date each time I reboot, like in the original DOS. :(
Happens every time I reboot. I don't know what I did to mess up the
filesystem time in the first place; I could provide details of what I
did with lfs, but it appeared to be the simple act of making a
directory and listing its contents.
