Minor Tweak

Little tweaks has been made on some files on /etc/rc.d/ directory, mostly rc.6 and rc.K files. Those two files are being executed when our system is rebooted or turned off (rc.6) and when Slackware is booted into a single mode (rc.K). Both has been tweaked to have better unmounting process with NFS partition.

There are no other updates left and the changelog is getting smaller and smaller each day. You don't want to have a breakage by introducing major changes in this phase of development.
