I'm also waiting for it in my work to make NDB pluggable. We have quite
a lot of options that can be specified on command line/my.cnf for NDB.
As a temporary gross hack, I've put the configuration options into a
table.
Of course, I haven't managed to get it all linking successfully yet*, so
I can't tell you if it works or not :)
[*] various libtool and automake foo seem to be slightly akin to finely
chopping onions with a really sharp knife - blindfolded and drunk;
perhaps i'm just not too knowledgable there though :)
