[CentOS] Appended 1 in fstab entries CentOS4.X installs

Im not dual booting nor triple booting. CentOS is the only OS on the system.
I have have to format and reload. I just select the partitions re-name them 
back to / or /boot etc..and select to format with ext3 patition type. I dont
actually select each partition and delete them then re-create them. I have 
always done this even in centos3 and I never had the problem in centos3.
Matter of fact I installed a true RHEL4 install and it does the same thing, 
also same result of RHEL3 as in centos3.
