The way you describe it sounds like you have a modeling issue with your system.
Committed transactions are not supposed to be rolled back.
Your System Architect has to arrange things in such a way that all the

I have a large series of mysql changes(inserts/deletes/updates) taking

, I restarted mysqld, which of
course caused a rollback of the alter table. The roll back is progressing at about 1% every 12
minutes, which equates to about 20hrs before the server can be back up - not a good thing. Reading

in such a way that
they need not rollback (only do so if the whole system stops).
One way that comes to my mind is to accumulate all data in some
temporary table, using some other value as ID (or in application
variables), and only after the final yes, do it confirmation transfer
them to the true tables
Andre,
I would recommend a table for recovering id's that are lost due to rollback.
Before you actually rollback, take the generated ID and push it into this
table. Then change the way you acquire id's on insert. You will want to
check to see if this table has an ID before you auto_increment
