-
- Answer the question "no" to make it go away until the next reboot,
- or "yes" to make it go away forever.
-
- That question happens only when lboot discovers that
- -hardware has been added to or removed from the system since
- the kernel, /unix, was last built, or
- -kernel softare has been added or removed from /usr/sysgen.
-
- When lboot is right, it is generally a very good idea to rebuild the
- kernel.
-
- However, there are cases when rebuilding the kernel is a bad idea,
- which is why it asks before taking the potentially dangerous step of
- rebuilding the kernel. For example, if you have written your own
- driver, you may not want to add it to the kernel, in case it is not yet
- ready for prime time. If you have removed a board from the system only
- to test something, you probably do not want to rebuild the kernel
- without the driver, and then rebuild it with the driver.
-
- Lboot can be wrong if the time and date on your system is or has
- been whacko. The most common problem is one or more of the files
- and directories /usr/sysgen, /usr/sysgen/boot, /usr/sysgen/master.d,
- /usr/sysgen/system, /usr/sysgen/boot/*, or /usr/sysgen/master.d/*
- has a date in the future; January in 2031 is popular. If this happens,
- lboot is unable to make /unix "newer" than the system software.
- The fix is to run the following two commands:
-
- find /usr/sysgen -newer /unix -print | xargs touch
- /etc/autoconfig -f.
-
- The first command fixes any bogus dates, and the second ensures
- that you actually have a newer kernel.
