That message should probably be more strongly worded. It is absolutely *imperative* that the custom kernel is upgraded before continuing with freebsd-upgrade install. For more information about how to upgrade to freebsd 8 see http://www.freebsd.org/doc/en/books/handbook/updating-upgrading- freebsdupdate.html > Then I was looking for the way of kernel upgrade, but found > nothing.

As you found out, you should never do that. Always make sure the kernel is the same or newer as world (userland) especially when upgrading to a new major version. > I made as > mentioned in hanbook: > # freebsd-upgrade install > # shutdown -r now > # freebsd-upgrade install At this point most userland utilities (because they all use libc.so) depend on features only available in the 8.0 kernel, while the installed kernel is still at 7.1.

You can try reinstalling 7.1 taking care not to repartition the HDD. If all went well the system runs a GENERIC kernel, which is upgradeable by freebsd- upgrade. You can then retry the upgrade process. This process (the reinstall from cdrom) will revert any changes to /etc, so you will need to restore that from backup. Perhaps others know a better/easier way. > > Thank's in advance for your help.
