Reply-To: 9front@9front.org Precedence: bulk Hi all, it's clear to me from the FQA how to compile the system from sourceces and upgrade the system. I've done it a few times in VMs in the past. Now that I have a stable system that I use every day, I'm more concerned I might break it. People here seem to be trying kernel patches all the time... so it must be possible to safely rollback in case of problems. How does one do that? Suppose I upgrade the system and it hangs on reboot; how does one rollback? I'll take this opportunity to add another question. I have a Unicomp Model M keyboard and sometimes I get spurious key repeats, see resulting =E2=80=9Csourceces=E2=80=9D typo above. It doesn't happen with= other keyboards (but I'd rather use this one). Any hint as to how I might debug this, or provide useful information? Thank you, Nicola
