[CALUG] how to install CentOS7 packages

[Walt Smith]

plus some gui useage   Q's ...


Hi,


The initial install looks nice, and many of the features
are MUCH more smooth and easy to use than before:
and the install looks a lot like Ubuntu:  the same Gnome 
Package manager ?

A big change from CentOS6.x  !!!!  



install DVD 1.
I installed a basic CentOS7 system, using the
DVD with the menu giving about 10 choices of
system types.  I picked Desktop or Workstation.

! don't know if I can re-use the DVD to install yet
another system type without erasing the existing
system.. Don't want to try without advice.
Generally, I just want to add more packages/features.

 Install DVD2 (iso)
I downloaded the "everything" iso, about 8 gigs.
The file roller looks good.
Is it possible to install the packages - rather - applications
from the gui package manager ?  or have the Package Manager
display the various applications on the iso ?

I'd  prefer not to install from scratch, and don't know what the 
other apps are on the iso !!  The gnome does show whats on the 
present install.

Do I need to setup the iso as a local repository ?

Is totem still the main media app?
What is the media codec situation ?

Has the revision/update system been overhauled to be
transparent ?  I know there was a CentOS7.3 built
( rather RHEL 7.3 )  but don't see any way to know which
version I have... other than maybe looking at the versions of
firefox, nautilus, other apps, etc...   I guess using a
command line is the only way to find which kernel ?

Lastly, the entire filesystem seems to have been overhauled.
There is now some "run" directory, and the main  "computer"
top directory in the gui only shows 50 gigs of a 250 gig drive...
Looks like root is organized differently ?  Home is about 200
gigs.  How do I simply find the drive size ?  And "free" for each 
partition ?   CLI is necessary ?


Inquiring minds want to know...


thanks!

Walt ..
