Hi. I'm trying to find a bulletproof way to tell whether a given file
is mounted on a non-local filesystem. I've been focussing on the
device number returned by stat(2), for which I have found empirically
on the SunOS and Solaris systems I have tested is:
0 or large number for local filesystem;
1 for AFS;
<0 for NFS;
and so if this investigation were actually borne out across all
platforms, all machines, my test would be
if (st_dev == 0 | st_dev > 1)
# local filesystem
else
# non-local filesystem
But I haven't been able to find any basis for such a leap of faith.
Does anyone have an answer handy?
