in a full P9 system, files are not stored locally; typically,
terminals are completely diskless. files are stored on and
protected by a fileserver. regular users cannot connect to
the fileserver without first authenticating themselves through
an auth server, so your files are safe from deletion.

you're thinking of P9 as a standalone, single system when it is,
in fact, a distributed system usually made up of several hosts.
