I experienced issues installing nfs-common package from official
maintainers jessie repositories during my jessie-backport reiser4
-patched Linux kernel efforts. Accordingly I jessie-backport'ed
nfs-common and nfs-kernel-server packages that you will find at:
https://sourceforge.net/projects/debian-reiser4/files/nfs-common-reiser4-bp/
As a matter of fact just uploaded jessie-backport'ed (kerberos)
krb5-1.15-1 package that I had built priorly -- as part of my initial
efforts building first 2 packages mentioned above.
https://sourceforge.net/projects/debian-reiser4/files/jessie-krb5-1.15-1_bp/
By the way none of those packages have *any dependencies* on reiser4
other than being built in a machine with that file system ;-)
You are welcomed to give those a try but I offer no guarantees whatsoever.
Best Professional Regards.
P.S. you may need krb5-config from Sid (Unstable) -- as the above are backports.
