You're shadowing /etc and /var what most likely explains the disparity (/etc/systemd/system is read before those mounts to start systemd-network and after the mount shows a completely different configuration)

Re: [SOLVED] NetworkManager.service does not start when login

You got it!
I have been running arch for 15 years with no major issues. I was surprised with this new  install and its issues. I tried in this new install to use BTRFS subvolumes and snapshots, which I never did before. And this is the root of all this mess. I didn't set up correctly my filesystem.

# btrfs subvolume list -p /
ID 256 gen 1922 parent 5 top level 5 path @
ID 257 gen 1922 parent 5 top level 5 path @etc
ID 258 gen 1925 parent 5 top level 5 path @var
ID 264 gen 43 parent 256 top level 256 path var/lib/portables
ID 265 gen 44 parent 256 top level 256 path var/lib/machines
ID 266 gen 90 parent 256 top level 256 path var/tmp
ID 267 gen 1925 parent 256 top level 256 path home/gabx.homedir
ID 270 gen 1121 parent 258 top level 258 path @var/lib/portables
ID 271 gen 1122 parent 258 top level 258 path @var/lib/machines
# cat /etc/fstab
# /dev/nvme0n1p5 LABEL=magnolia
UUID=aa276d53-410c-4bf4-ac41-08b658625043	/var      	btrfs     	rw,noatime,discard,compress=zstd:3,ssd,space_cache,commit=120,subvolid=258,subvol=@var	0 0

# /dev/nvme0n1p5 LABEL=magnolia
UUID=aa276d53-410c-4bf4-ac41-08b658625043	/etc      	btrfs     	rw,noatime,discard,compress=zstd:3,ssd,space_cache,commit=120,subvolid=257,subvol=@etc	0 0

I don't fully understand BTRFS subvolumes mechanisms and certainly did something wrong. As it is a fresh install, I will make a new one, with or without BTRFS subvolumes (will probably just stick to systemd homectl and forget /var and /etc).

Thank you so much for your help and patience.
