My question exactly.

Unfortunately, a Pixel tablet seems my only option for an alternative ROM. Fortunately my old Galaxy is still working fine.

I could use a 12” tablet, but only if I can install alternative ROMs on it.

Just ordered a new 7 a so it fits the expected hardware lifetime. 335 EUR is somewhat above my phone hardware price limit but moving from LineageOS to GrapheneOS is worth it.

Luckily there’s GrapheneOS for the Pixels. I’m thinking about buying a refurbished Pixel since my Poco X3 Pro with Lineage OS is having ghost touch issues. The only thing holding me back is less screen real estate.

Possibly, eventually. Right now I’m using some useful proprietary things from the Play Store, as well as GMail, shared calendar and Maps.

I’m getting too old to self host All The Things, but if Google insists to be a dick I’ll let most of it go and self host the rest.

I think these were the ones I installed https://wiki.lineageos.org/gapps/ My Poco X3 Pro has been having annoying ghost touch issues for a while, perhaps the time has come to look into an alternative.

I run LineageOS on my phone (with gapps) and my tablet (sans gapps). If Google tries deleting stuff it doesn’t own on my phone it’s LineageOS sans gapps for my phone and probably buying a phone for GrapheneOS.

https://wiki.debian.org/ZFS has nice docs. I would practice in nonproduction first if you’re unfamiliar with zfs.

No hardware RAID. Use zfs, if you can. Mirror the boot SSD. I would use a stripe over mirror and 4 HDDs. Two drives are not enough redundancy. Use enterprise or nearline drives, if you can. Debian is great, you can install Proxmox on top of it, but from the sound of it plain Debian would work for you.

NATO/Russia 3rd world war, still reasonably limited to just two countries, for time being.
