For legal reasons the two active files for using Soft Updates are in
/usr/src/contrib/sys/softupdates. To use them, copy them to this directory,
and add option SOFTUPDATES to your kernel configuration. You should read the
copyrights on the files and the README in that directory before doing do to
ensure that you are acting legally. The stub file here will allow the system
to function without this option turned on.
To turn on soft updates use the -n option of tunefs, on UNMOUNTED filesystems.
e.g. from single-user mode..
tunefs -n enable /dev/rsd0s1d
Soft Updates is ALPHA code. Use at your own risk.
