>Description:
If a machine's time is set to local time (for example, CET) and
not GMT, there is a potential that (not too dramatic, but still
weird) problems may occur during a make installworld process.
/usr/src/UDPATING therefore suggests that users running at local
time run "adjkerntz -i" after having booted into single user
mode and before starting the installworld process. However,
in order to read this suggestion in UPDATING, one would have
to scroll way down. Therefore, I guess the handbook should
probably include the "adjkerntz -i" statement as well, and so
I included it in the part that tells users how to boot into
single user mode, right after the commands that are supposed
to clean / mount the filesystems.
>How-To-Repeat:
Boot into single user mode using boot -s, install world, reboot
and notice that the files you have just installed are dated one
hour in the future (IF your machine is set to local time). Try the
same, but run adjkerntz -i before installworld and everything will
be fine. Browse through /usr/src/UPDATING and see that somewhere,
near the part on going from 3.x to 4.x, it also suggests local-time
users to run adjkerntz -i, so I guess we should do the same ;-)
(NOTE: To actually run into problems with this, you'd have to try
to install certain ports, which will fail until the timestamp of the
files installed by installworld is past ;-)
>Fix:
The following patch, applied to handbook/cutting-edge/chapter.sgml
fixes it ;-)
