According to the warning from the tune2fs man page this should be 
avoided for ext3/4:

Anyway, according to the description of the autofsck script, it only 
checks the mount count and not the dirty flag. Therefore it seems to be 
OK. However I prefer not to use the mount count but a time interval 
instead which is much more convenient for me.
