A Dell PowerEdge 530 serves as my house network’s
router, firewall, DNS and NTP server.
Today, pacman -Syu updated the Kea DHCP daemon
from Arch version 3.0.3-1 to 3.0.3-6.
The updated daemon wasn’t serving DHCP.
I bought a refurbished Dell 7420e laptop
to replace my aging Dell 7470.
The 7470 has an S key that works irregularly.
In the past, I have used xsane to run an HP DeskJet 2600 All-in-One Printer flatbed scanner.

Dell laptops have a “backlight”, and the letters on the black-body of the keys can glow under the right circumstances. Very handy when positioning your fingers on the keyboard when in dim rooms. After installing Arch Linux, the 7420e keyboard would not illuminate. The keyboard backlight worked, the POST flashed it during reboots.

After installing Arch Linux, the 7420e would not suspend when I closed the lid, it just stayed on, display lit up brightly.
I bought a 8-port Netgear GS308E switch. I plugged it in, and it worked, but I noticed the LEDs on the RJ-11 ethernet socket flickered regularly.
I use Arch Linux, a simple, lightweight Linux distribution. You should, too. It’s not hard.
One of the things Arch users do is update, regularly.
I find that weekly updates are adequate.
Running sudo pacman -Syu every 7 to 10 days keeps problems away.
What happens when pacman updates fail, or updated package downloads get really slow?
I looked in the systemd journals on my Qotom fanless server. I saw something reporting a Postgres database problem.
I set up two Raspberry Pi SBCs with GPS boards as NTP servers earlier this year. I used an oscilloscope to see how far apart the “pulse per second” (PPS) pulses that the GPS boards output.
