An unofficial Debian Installer for Pinebook Pro

[soloquintett]

I would like to report two issues i had:
1. Last night my pinebook (fresh debian install with kernel 5.5) crashed (froze, probably ran out of memory+swap) after forcefully restarting, i was dropped into the (intitramfs) shell. The only information i could find there, was that my root drive (nvme, linked from extlinux.conf) was not found. Booting from an SD card however shows the drive. I could decrypt it and save my data. Now i am reinstalling.. Did anyone experience this? It does not really bother me, but I worry if it will happen again in the far future, ruining my day..

2. Reinstalling, I decided I want btrfs-snapshot capabillity, to be able to recover from a broken rootFS. However changing the install script to

Code:

sudo mkfs.btrfs -L ...

instead of

Code:

sudo mkfs.ext4 -FL ...

Does not boot.

creating a normal ext4 root partition and copying the content

Code:

sudo cp -ar /mnt/mmcblk2p6 /mnt/btrfs_nvme

also does not boot.

So is btrfs not supported by initramfs?

Any inside would be great.
Thank you!
