Runnning old "Fedora 20-x86_64", and want to install Fedora-Kde-live-25-1-3.

Situation:
$ uname -rov
3.19.8-100.fc20.x86_64 #1 SMP Tue May 12 17:08:50 UTC 2015 GNU/Linux

$ sudo lvmdiskscan
/dev/fedora/root [ 50,00 GiB]
/dev/fedora/swap [ 3,77 GiB]
/dev/sda2 [ 500,00 MiB]
/dev/vg_maq01/lv_swap [ 5,75 GiB]
/dev/sda3 [ 118,75 GiB] LVM physical volume
/dev/vg_maq01/lv_home [ 63,00 GiB]
/dev/vg_maq01/lv_root [ 50,00 GiB]
/dev/fedora/home [ 48,48 GiB]
/dev/sdb2 [ 500,00 MiB]
/dev/sdb3 [ 194,87 GiB]
/dev/sdb4 [ 500,00 MiB]
/dev/sdb5 [ 102,24 GiB] LVM physical volume
6 disks
4 partitions
0 LVM physical volume whole disks
2 LVM physical volumes

The /dev/sda* is a SSD(KINGSTON SV200S3128G) 128GB, with old "Fedora 16-x86_64", and only want to recover some files in /home.

The /dev/sdb* is a Seagate(ST3320613AS) 320GB, running old "Fedora 20-x86_64", with some important file in /home.

$ sudo lvscan
ACTIVE '/dev/fedora/swap' [3,77 GiB] inherit
ACTIVE '/dev/fedora/home' [48,48 GiB] inherit
ACTIVE '/dev/fedora/root' [50,00 GiB] inherit
ACTIVE '/dev/vg_maq01/lv_swap' [5,75 GiB] inherit
ACTIVE '/dev/vg_maq01/lv_home' [63,00 GiB] inherit
ACTIVE '/dev/vg_maq01/lv_root' [50,00 GiB] inherit

$ mount | grep /dev/mapper
/dev/mapper/fedora-root on / type ext4 (rw,relatime,seclabel,data=ordered)
/dev/mapper/fedora-home on /home type ext4
(rw,relatime,seclabel,data=ordered)

Problem:
Want to mount the SSD on "Fedora 20" to recover some files, copying it to /dev/sdb3 space(/dev/sdb3 not used/mounted). After this, I can erase all SSD and install "Fedora 25" on it.

Thanks for help.

How does one get a clean installation of Fedora? "Clean" means that only those packages are installed that are actually needed and only those services are running that are actually needed.

Installed Fedora 26 on recommendation of a Scribus developer. Installed about 30 packages per his advice.

But when I try to compile a program the machine can't find C++. So what is the package I need to install to compile C++ programs?.

Another question. On Slackware (yes I am one of those) I can use kdm to get to a window function ( I preferXFCE). How do I set up a window manager in Fedora and how do I access it?

For some reason I have to temporarily deactivate IPv6 interface configuration on a F22 server box.

According to documentation (or at least as I understood) it could be done either by adding

IPV6INIT=no
IPV6_AUTOCONF=no
to /etc/sysconfig/network-scripts/ifcfg-eth0

or

NETWORKING_IPV6=no
IPV6_AUTOCONF=no
to /etc/sysconfig/network

I tried both, executed "nmcli c reload", "systemctl restart NetworkManager", even rebooted the system. No change in network configuration. In ifconfig I have a local link address as well as a global address as advertised by the router and autoconfig based on mac address.

All those options are documented in usr/share/doc/initscripts/sysconfig.txt, so I guess these are still valid options.

Now I am wondering what I may have overlooked or missed?

Any hint appreciated.
