Installing splack-current

splack-current does not yet have a working installer.
Here is a hack to install splack-current on machines which are supported by the 2.2.20 kernel used by splack-8.0
This will not work for newer machines such as the SunBlade and SunFire series.
First install splack-8.0, you only need the a and n series packages.

Make a directory for splack-current and download splack-current from a suitable mirror. You could also use an NFS mount if you have a copy on another machine.

cd splack-current/splack/a
installpkg glibcsolibs (You MUST do this first)
installpkg sed
installpkg pkgtools

upgradepkg *.tgz
silo

Now you can cd ../n and upgrade the network packages
Then install any other packages from other sets.

Finally reboot and download kernel sources 2.4.27, compile, make, and enjoy.
2.4.27 works on everything except Sun4D SMP, I have patches to fix this.
