Some of you may remember over a year ago when I proposed the concept of Tumbleweed Snapshots [1] and later the prototype that I provided [2]. Today I would like to announce hosting for the snapshots, that is not inside my house :), and ready to use!
For those not familiar with the concept I will describe it in the form to which it has evolved.
Tumbleweed, being a rolling distribution, is constantly changing and packages are constantly being rebuilt against one another and updating requirements. As such it becomes necessary to update even when undesirable. For example, one is running snapshot 17 and the next day snapshot 18 contains a QT update that rebuilt a large number of packages. When attempting to install an application that depends on QT one is greeted with an ugly unresolveable error. It is then necessary to run a full update, likely very large with many unrelated changes, in order to simply install an application as would have been possible yesterday.
Certainly a nice helping solution, but keep in mind that bug reports coming from such a 'mix-and-mash' upgrdaed TW setup will simply not be handled. There have been numerous times reports about libraries that changed in incompatible ways without changing their soversion. Such things will bite you even more often.
Let alone that a new library is perfecly allowed to add functions without changing the so-version. A binary built against the newer lib might make use of this new functions. The dependency will, nevertheless, be on libFOO<NUM>, with <NUM> not having changed, yet your application not starting in the end.
Tumbleweed snapshots are a tested unit; the same trouble you keep on running in while running 'zypper up' instead of 'zypper dup' will bite you here. And I for one will always ask for 'zypper dup' on a bug if this setup is being used.
But he's just trying to continue using an older snapshot, not a mix&mash as far as I understand.
