[Linux-cluster] safe to remove old pkgs?

[RR]

Hi all,

I had initially installed CentOS 4.3 on a machine with the
corresponding CSGFS pkgs. Then further went to upgrade the system to
CentOS 4.4 with the corresponding CSGFS pkgs but just realised that
the old kernel and CSGFS pkgs are still there. Is it safe to remove
them? As in when I do,

> yum remove kernel-2.6.9-34.0.1.EL kernel-smp-2.6.9-34.0.1.EL

and get

Is this ok [y/N]:

Can I safely say "y" here?

Thanks
