for one simple desktop, but realize your desktop is not the world
but that does not interest me in any way and even on my desktop
a dvd-upgrade is unacceptable because if something goes wrong
you have no control
after a yum upgrade you can verify that the most important
things are fine BEFORE reboot (bootloader-config,
package-cleanup --problems, ....), optimize/correct things
you know are not fine after the upgrade (active services
after transition to systemd as example) and then you reboot
ONCE in a clean starting system instead a boot in the blue
____________________________________________________
a dist-upgrade with yum can be made wihtout ANY DOWNTIME after
rebuild core services like httpd so that they get not restarted
while updateing and so the only downtime is the normal reboot
i am using a build/test-environment (VM guests in production)
and after confirming that the upgrade is running smooth which
is simple when no machine has access to any other repo than
the internal build/cache-repos the upgrades are done AUTOMATICALLY
it takes 5-6 minutes per production server and a reboot per
server takes around 30 secondes
so please do not tell me downloading a dvd is a valueable
option if you are not speaking about a unimportant desktop

this way dist-upgrades working SINCE YEARS and if such things
are broken this is NO IMPROVEMENT in any way!
