qcom-armv8a: use PARTLABEL for rootfs instead of hardcoded node (#1681)

ricardosalveti · web-flow · commit 30e47cfa93b5 · 2026-03-05T16:28:18.000-03:00
This change updates the machine configuration to use PARTLABEL for
selecting the root filesystem instead of a hardcoded device node. The
root filesystem was previously identified using a fixed device node (for
example /dev/sdaX).
