man and man-db inconsitency between centos 6 and centos 7?

+1 vote
154 views

I use "yum list installed" to determine if a package has been installed on centos. In particular, I was interested in the "man" program, installed with the command "yum install man".

In Centos6, if I look at the results, I see that "man" was installed. This is good.
In Centos7, if I look at the results, I see that "man-db" was installed. This is inconsistent.

The result is that the generic algorithm:

if I want package X , check the "yum list installed" output.
If X is not listed, install it, otherwise assume it's already installed.

Is there a reason for this inconsistency? The above algorithm works with most other packages.

what 'algorithm' ? there's no fixed correlation between program name and package name.

for example, the package providing 'iostat' and 'sar' is called sysstat.

And, some packages change their names in different major releases of an OS. Some packages are dropped entirely in new releases, and other packages are added.

I tried to install CentOS 7 on a new system. It works.

However, I'm noticing small things:
1. system-config-network-tui is not installed and yum cannot find it. I realized for this -- nmtui
2. What about firewall? I can't seem to understand the replacement from system-config-firewall-tui

I'm trying to install Centos 6.4 under Virtualbox on a Mac running Lion. I downloaded the 2 iso DVD files and set Virtualbox to boot from DVD 1

When I start the vm it puts out a lot of messages then asks me what kind of install I want to do. I select the basic install and it tells me it found the media ( the iso DVD file I downloaded) puts out a message about the anaconda ( I think) install starting then goes to a screen with the Centos 6 logo and appears to do nothing. No more messages appear.

Should I be using the minimal iso install file?

I have installed Windows XP, 7 and 8 under Virtualbox and they all work. I also installed Ubuntu but didn't like it so I removed it and thought I would try Centos

Does anyone know what might be going on and how to get it working?
