+ Mnesia could crash if mnesia:add_table_index/2 was

+ Add {majority, boolean()} per-table option.</p>
+ <p>
+ With {majority, true} set for a table, write transactions
+ will abort if they cannot commit to a majority of the
+ nodes that have a copy of the table. Currently, the
+ implementation hooks into the prepare_commit, and forces
+ an asymmetric transaction if the commit set affects any
+ table with the majority flag set. In the commit itself,
+ the transaction will abort if it cannot satisfy the
+ majority requirement for all tables involved in the
+ transaction.(Thanks to Ulf Wiger)</p>

+ Call chmod without the "-f" flag</p>
+ <p>
+ "-f" is a non-standard chmod option which at least SGI
+ IRIX and HP UX do not support. As the only effect of the
+ "-f" flag is to suppress warning messages, it can be
+ safely omitted. (Thanks to Holger Wei�)</p>

+ Mnesia sometimes failed to update meta-information in
+ large systems, which could cause table content to be
+ inconsistent between nodes.</p>
