Hey
@wizardfromoz , thanks for the ping.
Basically, on Leap systems,
zypper up or YaST Software like
this for package updates
within the same release version. For upgrades, i.e. Leap 15.2 -> Leap 15.3, it would be
zypper dup
On Tumbleweed, every release is like a new major version, so it's recommended to use
zypper dup
The difference between
zypper up and
zypper dup is that
dup will allow packages to be deleted or be changed to a different repository if it no longer exists in the previous repository it was installed from.
openSUSE did not provide for a Live environment install (has that changed?)
Not really. The live ISOs do have an installer now, but it just loads the net-install module (very very slow to initialize and update itself), which downloads all the RPMs from the openSUSE repos and installs them one by one onto the target system. This is different from most live systems like Ubuntu, Manjaro, and GeckoLinux, where the installer decompresses the same filesystem that is running on the live system, so much much faster.
