The reason I suggested (nfs) was that long ago I had issues with 
both the pi2b & pi3b read/writing to usb in an OS context.
The breakage becoming particulatly obvious in a read/write of small
files situation, like git clone.

I put it down to the usb2 ports [1] on both boards not really being
up to this OS task. nfs negates this issue, even though the port is only
100Mbit.

The issue is not present on fast media plugged into the usb3 port of
a pi4. I have not tested something like a git update on the microsd
but I'd expect the same issues as encountered on the pi2b & pi3b usb,
because the microsd media isn't designed for fast small reads/writes.
I'd expect errors.

[1] maybe the boards in general.
