Personally I use corporate-like naming scheme for my devices, the format is:

[AABB-CCCC-DDEE]

AA: Location of the device - HQ (home), CL (cloud).
BB: Role of the device - HV (hypervisor), SV (server), NW (network) and workstation (WS).
CCCC: Device brand (for NW), application running (for SV), and workstation purpose (for WS).
DD: For server and workstation - OS running on the device (WN=Windows, LX=Linux, MA=macOS). For network device - their role on network (RT=router, AP=access point, SW=switch).
EE: # of the device, year of purchase for WS.

For example, here’s my router, KASM server and my gaming PC hostnames:

HQNW-UBNT-RT01
HQSV-KASM-LX01
HQWS-GAME-WN16

Still trying to optimize this naming scheme, like removing all the dash, but currently too lazy to do it lol.

It was okay on my old T460 which only has 56% of its original capacities. Got about 1.5hrs with sys-* and personal/work VM running. For me it’s a tinkerer distro rather than privacy distro, because every time I use my laptop, I tend to find new problems haha. Oh also it sucks when connecting to public WiFi with captive portal.

Pihole is a good start, though I personally use my Pi 3B+ for printer server over WiFi since I have a dumb Epson printer.
