Getting rid of huge ibdata file, no dump required

You have been told (guilty as charged), that the only way to get rid of the huge InnoDB tablespace file (commonly named ibdata1), when moving to innodb_file_per_table, is to do a logical dump of your data, completely erase everything, then import the dump.

Seriously, Ubuntu, upgrading between versions has become just painful… I waited a few weeks before I upgraded from Xubuntu 11.10 to 12.04 because the upgrade last time completely hosed my system and left me with a borked X configuration. This time, I upgraded and now all my keyboard shortcuts don’t work. None of them. I mean, they appear in my Keyboard Settings –> Application Shortcuts, but none of them work anymore. Seriously, WTF.
