Expanding the file system on the first boot of a fresh Raspberry Pi OS (buster) - or expanding it at all - has always been under discussion and there is a lot of material out there for how to do it.
But now, with the recent Raspberry Pi lite images, for me it looks like the file system is already expanded to max. When I check my disks with
df -h, my root partition is
7.x MB on a 8 MB SD card, and
15.x MB on a 16 GB SD card. That's already all I need, right?
Is automatic resizing done automatically nowadays?
