On the one hand we could first prepare mariadb package (package review 
is frozen for a while, but I'll try to push that forward soon), but on 
the other hand we should know how we want to ship it -- and package it 
according to that.

This is why I'd like to refresh this topic, which froze too in a state 
with no resolution (at least I haven't noticed any).

What I'd like to achieve is to collect real risks (or pros & cons) of 
all possible solutions. Right now I see these options:

1. continue shipping only mysql
2. ship mysql + mariadb, that would conflict
3. ship mysql + mariadb with adjusted file-names and using alternatives
4. ship mysql + mariadb with adjusted file-names but not using alternatives
5. drop mysql and ship only mariadb
6. is there any other?

The following are notes I tried to summarized mainly from the thread 
started at
(+ some of my POVs)

ad 1. continue shipping only mysql:

* Admins would be happy (unless they care about early security updates, 
fixes and regression tests -- so probably not happy that much)

* No early (not only) security fixes
* No new regression tests
* It doesn't seem to me mysql upstream will ever become more open, the 
opposite is much more probable.

NOTE: Considering just changes made by Oracle during the last year made 
on mysql project I'd say we should only think about *how* and *when* 
switching to an alternative, not *if* anymore.

ad 2. ship mysql + mariadb, that would conflict:

* Probably the easiest way to do at least in the beginning.

* It would require twice much work to maintain two packages.
* What message would we send to users - that we don't know what we want?
* In a long term it doesn't look sustainable.

NOTE: It could be used in a transient period, e.g. during one release.

ad 3. ship mysql + mariadb with adjusted file-names and using alternatives

* To give an option to admins? I'm not really sure if this is even good.

* cons from 2. apply here
* I don't think this is actually possible. Alternatives work fine with 
commands, but I haven't seen a usage of this tool for libraries and 
* That would also require 100% API/ABI compatibility of libraries, which 
we can't depend on.

4. ship mysql + mariadb with adjusted file-names but not using alternatives

* We could provide both packages at the same time without conflicts

* cons from 2. apply here
* We don't want to differ from upstream
* What package depended packages would be built against?

ad 5: drop mysql and ship only mariadb

* We'll provide a package with active and open upstream, that cares 
about (not only) security bugs...
* Some enhancements in comparison to mysql

* Transition could be harder, we would have to take this like a rebase 
(we probably can't depend on 100% API/ABI compatibility).
* Admins would have to migrate.

NOTES: Similar will happen soon or later (at a time of rebasing to 
Right now my favorite one.

So what have I said wrong/omitted?
