ROCKPro64 - Anpassen resize_rootfs.sh
-
Nachdem wir nun von der PCIe NVMe SSD booten können, haben wir ein Problem, die Root Partition ist zu klein. Diese muss vergrößert werden.
Macht das bitte erst auf einem Testsystem!!!

Konnte Kamil davon überzeugen, das das eine gute Idee ist. Wir sind ja alle ein wenig faul

Seit Release 0.10.10 ist das automatische Vergrößern der Root Partition mit drin
- 0.10.10: Support automated resize when booting from nvme
Einfach das Image auf die NVMe SSD schreiben, ab in den ROCKPro64 und fertig! Nach dem Booten wird die Partition dann automatisch auf die maximal mögliche Größe erweitert.
Kamil hat das Script auch ein wenig angepasst.
