Hi,
I was tracking down a Debian/Ubuntu bug with nfs-utils 2.6.1 where in
one case, after installing the packages, you would end up with
rpc_pipefs mounted at the same time in two locations: /run/rpc_pipefs
and /var/lib/nfs/rpc_pipefs. The /run location is what debian/ubuntu
default to.
After poking around a bit, I think I found out why that is
happening[1], but it led me to ask this question: why is
var-lib-nfs-rpc_pipefs.mount (and its corresponding rpc_pipefs.target
unit) still shipped, given that nfs-utils now has a generator?
Could just be an oversight, or perhaps a better reason exists. The
nfs-utils userspace has to handle a lot of different cases and legacy
setups.
Steve D, do you know?

Shouldn't the generator be enough for all cases, where rpc_pipefs is
mounted in the default compile-time location, or changed via a config
change to nfs.conf? I know currently it checks[2] whether the config
points at the default location, but that check could just be skipped
and then the generator would always produce the correct mount and
target units.
