Ok so I am new to Linux and though usermod -G would amend the current settings and just add the new group, not overwrite them all... so sue me

anyways I attempted to add the root user to a backups group and overwrote all its group settings... does anyone know the default root groups for RedHat 9 / cPanel5?

I have so far, but not sure if I am missing any:
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),32009(backups)
thanks
