Comment # 44 on bug 429326 from Ancor Gonzalez Sosa

yast2-nfs-client has been modified to not longer use its own buggy /etc/fstab
parser/writer. Starting with yast2-nfs-client 4.0.6 it will use the
parser/writer provided by libstorage-ng, which handles comments correctly.

So 10 years after... finally closing this bug as fixed!
