Eh? The only commonly used filesystem that doesn't support online growing
is vfat (and it's used only because of @#$$%^&* Windows and @#$%^&* EFI).

Legacy filesystems like ext4 also allow growing only (no shrinking) but in
this use case the image needs to be pre-shrunk before transport for other
reasons anyway, so that's not a concern.

I haven't used Raspberry is a long long while (there's plenty of other SoCs
both cheaper+saner, or more performant+featureful -- often above cheap
regular desktops (like NUCs)), but IIRC raspi-config uses ext4 with online
grow. Other images do ext4 or f2fs, also in an init script (or the worse
alternative...) during first boot.
