University of Toronto ☛ Linux software RAID and changing your system's hostname
Today, I changed the hostname of an old Linux system (for reasons) and rebooted it. To my surprise, the system did not come up afterward, but instead got stuck in systemd's emergency mode for a chain of reasons that boiled down to there being no '/dev/md0'. Changing the hostname back to its old value and rebooting the system again caused it to come up fine. After some diagnostic work, I believe I understand what happened and how to work around it if it affects us in the future.

University of Toronto ☛ The history of inetd is more interesting than I expected
Inetd is a traditional Unix 'super-server' that listens on multiple (IP) ports and runs programs in response to activity on them. When inetd listens on a port, it can act in two different modes. In the simplest mode, it starts a separate copy of the configured program for every connection (much like the traditional HTTP CGI model), which is an easy way to implement small, low volume services but usually not good for bigger, higher volume ones. The second mode is more like modern 'socket activation'; when a connection comes in, inetd starts your program and passes it the master socket, leaving it to you to keep accepting and processing connections until you exit.
