I found that under 4.2, if I modified the ifcfg scripts with an editor that
left a backup file with a name that began with the old name (i.e.,
ifcfg-eth0 & ifcfg-eth0~), that it would run ALL the scripts in directory
order. Hence, it would run ifcfg-eth0~ last, putting the old setup info into
my network config. Delete any backup files, or rename them so that they
don't begin with 'ifcfg'.

yep, I'll bet it's running your old config from the backup files.....
