Done with reboots for the night.
These reboots fixed various software flaws that Wikileaks revealed the CIA used to gain access to Linux systems.
In addition, I took some time to debug some of the systemd start up scripts which is why I rebooted some of the servers several times. There are still MANY bugs in these scripts to fix but a lot are fixed in Ubuntu 16.10, and probably even more in 17.04.
I am working on upgrading the failed server although I haven’t decided which CPU to go with yet, either an i7-7700k, a lot like the i7-6700k except less heat, or a Xeon of some sort. In the past I’ve avoided Xeon’s because the registered ECC memory was both expensive and slow as snails. No point in a fast CPU if the memory system can’t keep up. But now they have Xeon processors with a memory system based upon the X99 chipset that use normal DDR4 memory and flies. So considering going that route.
When I get the server together with the new hardware, I will try loading 17.04 on it, and if it works well, upgrade the existing machines.
