Hi!
I have suse 11.
Should I use “zypper up” od “dup” command ?
Which is safe ?
Thanks
I think you don’t want to use dup; that’s a new feature for example upgrading 11.0 to 11.1 (when it becomes available) I believe. I’ve always used up.

Ken-yap, that only holds true if you have the factory repository listed (zypper lr). -I think- 
Have been using up & dup happily so far, if I get burned you’ll be the first to know… GRINN
@miroslavmarecic : I’m not sure what exact difference there is between up and dup, but I’m rooting for the security/critical updates (up) and recommended and general updates from official openSUSE repros (dup).
There has been some discussion about this and it would be nice if one of the developers finds some time to elaborate on the zypper functions. Starting 10.3 & 11.0 there have been many additions to what zypper can do.
Cheers,
Wj
Well the man page for zypper said this:
dist-upgrade (dup) [options] Perform a distribution upgrade. This command performs an update of all packages with a special resolver algorithm which takes care of package splits, pattern and product updates, etc.
To me that sounds ominously like Debian’s dist-upgrade. Things like package splits happen at version changes. But you’re are probably right that you need certain repos registered for a dist-upgrade. Well do send us some updates about 11.1alpha.

zypper dup ignores repository priorities, so I would not use it if isn’t needed.
I expect Packman and Build Service repo to do things like package splits… but so far no problem with “up -t package”.
