If anyone really needs to do this, there is a patch in the gdm srpm called plymoth.patch that changes the parameters. It's located on line 225. If you change that to what you need and recompile it, it should work. Not that I recommend this...

Unfortunately in CentOS6 this is not the case. It completely ignores anything put into custom.conf as far as I can tell. It appears to run with -nr -verbose -auth -nolisten tcp by default. Is there any way to modify this? Regards, Stephen Jamieson
