CentOS

HI,

how can I extect only the rhel rpm from DVD1 and DVD2 of centos?
I noted that thare are a lot of not standard RHEL rpms in centos DVD.

I would to install a system that doesn't use third party rpms; the best way, in my opinion, is to create a personal repository that contains only the rhel rpms.

so, how can I extect only the rhel rpm from DVD1 and DVD2 of centos?

Many tnx in advance,
Stefano

There are only RHEL derived RPMs on the CentOS DVDs. There are no third party RPMs there at all.

Some of the RPMs there are rebuilt with names that contain ".centos." to show that those are the ones that have been altered by CentOS from the RHEL ones. The alterations all have to do with either removing branding (i.e. RH logos and/or other copyright material) or that use features that are specific to RH like RHN (licensing checks etc). You can find more information about which ones are modified in the CentOS Release Notes.

I compared the number of rpms in RHEL DVD with the number in CentOS DVD:

[root@xxx]# ll centos-6.4_64/Packages/ |grep rpm |wc -l
6381

[root@xxx]# ll rhel-server-6.4_64/Packages/ |grep rpm |wc -l
3720

so the are a lot of rpms that are not included in RHEL dvd; which kind of rpms are there? How can i choose only the rpms that are included also in RHEL iso?

Thank you so much,
Stefano

I think you will find that the RPMs on the RHEL DVD are those from only the base channel. CentOS does not license different features separately, unlike Redhat. CentOS takes all the publically available SRPMs for all the RHEL "channels" and rebuilds them. So, for CentOS, there is no separate base, desktop, virtualization etc channel, it's all included.

ok, thank you TrevorH
