Thanks to everyone for the feedback. The biggest criticism to this approach has been that /var is not encrypted. My practice of only encrypting /home and using rc.local to setup /home at boot would not seem to work for /var as /var is needed long before rc.local is executed. Is anyone using vnconfi

If you have enough memory you can avoid the /tmp problem by moving it into RAM: fstab: swap /tmp mfs rw,async,nodev,nosuid,-s=200 0 0 This will also speed up some things that write to /tmp. But keep in mind that in case of a crash the content is lost (if this is relevant for you). regar

Maybe it's more usefull encrypted a file IN the /home partition and move the 'shit' there, then you create symlinks (ln -s) to the encrypted file and done. 2009/10/30 Brad Tilley : > I wrote some notes on how I normally encrypt /home on OpenBSD laptops. > I was hoping misc could read it and bash i
