Suggestion, do not install any app you don't need, the less apps you install the more stable the Umbrel OS will be.
Discussion
thanks for the tip! I was hoping for Bitcoin Core, Lightning Core, Electrum Server, Samourai Server and Nostr Relay. I am using a Lenovo T420 ThinkPad with i5 2.6 CPU, 8GB RAM, 1TB SSD, - Trisquel GNU/Linux as base operating system and installed Umbrel on top of it with the curl command.
MyNode was great but i only got it to boot by luck earlier this year and needed to reflash the drive and can no longer boot the OS
Blockchain download at 20% now with umbrel, looking forward to it.
Looking at your config and the apps (good choices), you are good to go!
I am tempted to install this on my umbrel server.
any thoughts?

It hangs and causes serious problems , I had it for about a year, had to restart my nodes quite often, every three weeks approx... Once I remove it never a problem again. A router with AdGuard built in is the ideal condiguration.
But give it a try, your HW setup may be able to manage it without intermitent issues
How is it going with your PiHole experience?
I read you asked about Umbrel best config, I play with it for a while and have two of them installed in different locations running smooth with almost no maintenance required. But only after I removed all apps and left exclusively the Bitcoin Node Core, Electrum Server, Dojo Server and Tailscale.
