Slow server install, quirky nohup on Raspberry Pi Zero W

[LorenAmelang]

I finally have a Trilium server!

Installing Docker on my Raspberry Pi Zero W with current Debian Bullseye failed miserably:
docker/for-linux#1347
docker/for-linux#1349

Seems there is no Packaged Install for armhf, so I tried Manual Install:

pi@raspberrypi:~ $ wget https://unofficial-builds.nodejs.org/download/release/v14.18.3/node-v14.18.3-linux-armv6l.tar.xz

pi@raspberrypi:~ $ sudo apt install libpng16-16 libpng-dev pkg-config autoconf libtool build-essential nasm libx11-dev libxkbfile-dev

pi@raspberrypi:~ $ wget https://github.com/zadam/trilium/archive/refs/tags/v0.49.5.tar.gz

The build looked normal for awhile, but then:

> better-sqlite3@7.4.5 install /home/pi/trilium/trilium-0.49.5/node_modules/better-sqlite3
> prebuild-install || npm run build-release

prebuild-install WARN install No prebuilt binaries found (target=14.18.3 runtime=node arch=arm libc= platform=linux)

--> Long pause again...

The server works, so I guess these are not serious problems. But I suspect I will have to redo this long process every time the "Sync" version changes, so I'm wondering if there is a way to avoid the long pauses.

There was one other huge time sink in the installation:

pi@raspberrypi:~/trilium/trilium-0.49.5 $ nohup node src/www &
[1] 11818
pi@raspberrypi:~/trilium/trilium-0.49.5 $ nohup: ignoring input and appending output to 'nohup.out'
<-- The SSH terminal does not automatically show a new prompt here, the command just stops

If I leave the screen like that and close the terminal, the nohup fails, the Trilium server is no longer running.

If I press Enter before closing the SSH terminal, I get a normal prompt and the Trilium server remains active.

I can't imagine an explanation, or find one on the internet, but after over an hour of struggle, that seems to be how it works here.
