You don't need to specify "defaults" when there is any other option |
| 13 |
present. Defaults is just there so that the column is not empty if you |
| 14 |
do not specify any option. |

noatime implies nodiratime. Specifying both is redundant. |

Swap on SSD would be faster but I guess you want to avoid the additional |
| 25 |
writes. |

For home, auto_da_alloc trades a little performance for additional |
| 32 |
security against stupid applications that forget to fsync(). |
