[CentOS] removed items from removing postfix

Here are the items removed when removing postfix:

Nov  1 09:56:59 localhost yum[22042]: Erased: google-chrome-stable
Nov  1 09:57:00 localhost yum[22042]: Erased: redhat-lsb-compat
Nov  1 09:57:00 localhost yum[22042]: Erased: redhat-lsb
Nov  1 09:57:01 localhost yum[22042]: Erased: redhat-lsb-graphics
Nov  1 09:57:01 localhost yum[22042]: Erased: redhat-lsb-printing
Nov  1 09:57:02 localhost yum[22042]: Erased: redhat-lsb-core
Nov  1 09:57:03 localhost yum[22042]: Erased: sysstat
Nov  1 09:57:04 localhost yum[22042]: Erased: crontabs
Nov  1 09:57:05 localhost yum[22042]: Erased: cronie-anacron
Nov  1 09:57:06 localhost yum[22042]: Erased: cronie
Nov  1 09:57:07 localhost yum[22042]: Erased: postfix

Seems odd to me that those items would need to be removed just because
postfix is removed.

Thanks,
