I guess the client library remains compatible or do we need to recompile 
packages? ATM we also provide MySQL 5.6 by packaging the percona fork. 
It provides the mariadb version as well, is that still sensible with 10 
starting to be incompatible with mysql?

Why is it recommend to reload from a dump? Some more details would be 
good, as this is not easily doable (without a longer downtime) for users 
with large databases.

Well, we provide this with our current 5.5 packages? What happens to 
those who use this? Instead of the "I am sorry.." part, better link to 
the upstream bug report.

In addition to this, is the gcc 4.9 issue reported somewhere and the 
"workaround" confirmed? This bug seems to destroy the db files, so we 
better be sure.
