What I've read is that I/O on the raspberry Pi is terrible, but if the
directory fits entirely into RAM, I guess this isn't much of an issue. I
see only upsides to always running an AD-DC in a linux container,
regardless of what hardware you use. Filesystem-independent snapshots
are a very useful feature, and this makes it trivial to migrate your DC
from one hardware platform to another. And in this case using the
hardware for other purposes is expected.
