Why ispconfig uses MyISAM?
...and can I convert all tables to InnoDB without breaking ispconfig?
The reasons to ask are two:
1. On mysql crash tables can be corrupted and must be checked. It happened to me once.
2. I want to use Percona XtraBackup, but I have a problem, which may be caused of MyISAM tables (I think it completely locks MyISAM tables during backup, which can take long time)
