Bug description:
Feature request:
On InnoDB startup, check whether the iblog files exist, and what size they are.
Feed that size back into the innodb_log_file_size, regardless of what it was.
If it was different, you can write a warning to errorlog, but no error/abort.

This little tweak would allow us to increase the default log file size, without breaking existing installations.
