After last update of Tumbleweed i cannot mout a nfs share. Message:
jzl@jizbox:~> mount /nfs/Video
mount.nfs: Failed to find 'tcp' protocol

In /etc/fstab is
jizlast.vitaz.loc:/volume1/Video        /nfs/Video      nfs    
noauto,users,noatime,nolock,hard,vers=3,proto=tcp,local_lock=all,nordirplus 0 0

Versions:
jzl@jizbox:~> uname -a
Linux jizbox 5.4.14-2-default #1 SMP Thu Jan 23 08:54:47 UTC 2020 (fc4ea7a)
x86_64 x86_64 x86_64 GNU/Linux
jzl@jizbox:~> rpm -q nfs-client
nfs-client-2.3.3-11.1.x86_64

Than I made two links:
ln /usr/etc/protocols /etc/protocols
ln /usr/etc/services /etc/services

and now mount.nfs works OK.
