Package: nfs-common
Version: 1:1.3.4-1
Severity: important

Even after fixing nfs-config.service (see #848145), I could no longer
use my NFS 3 mounts because rpc.statd failed to start:

,----
| /usr/sbin/start-statd: 10: exec: 200: not found
`----

That's because dash, unlike bash, does not support file descriptors
higher than 9 in redirection and treats the command as if it had been
"exec 200 > /var/run/rpc.statd.lock".

According to POSIX.1-2008[1], you cannot rely on a number higher than 9
here:

,----
| The largest possible value is implementation-defined; however, all
| implementations shall support at least 0 to 9, inclusive, for use by the
| application.
`----

Indeed, using 9 rather than 200 actually works.
