The statfs structure has been updated with 64-bit fields to
allow accurate reporting of multi-terabyte filesystem
sizes. You should build world, then build and boot the new kernel
BEFORE doing a `installworld' as the new kernel will know about
binaries using the old statfs structure, but an old kernel will
not know about the new system calls that support the new statfs
structure.
Note that the backwards compatibility is only present when the
kernel is configured with the COMPAT_FREEBSD4 option. Since
even /bin/sh will not run with a new kernel without said option
you're pretty much dead in the water without it. Make sure you
have COMPAT_FREEBSD4!
Running an old kernel after a `make world' will cause programs
such as `df' that do a statfs system call to fail with a bad
system call. Marco Wertejuk also reports
that cfsd (ports/security/cfs) needs to be recompiled after
these changes are installed.
****************************DANGER*******************************
DO NOT make installworld after the buildworld w/o building and
installing a new kernel FIRST. You will be unable to build a
new kernel otherwise on a system with new binaries and an old
