Since the latest nfs-utils package in FC5 updates got an epoch of 1 set because of the release field problems, the current package in FC development (to become FC6) also needs its epoch to be set to 1 in order to preserve the upgrade path from FC5 to FC6.
Why, since the nfs-utils in FC6 will be version 1.0.9?
Because a higher epoch always wins : 1:1.0.8 > 0:1.0.9
Looks like Warren fixed this today. See the comment in bug #196359. Don't forget to learn how rpm's E-V-R (epoch, version, release) comparison works, as being careful could have avoided this problem entirely.
