Sure why not. However, if you plan to swap constantly, I'd recommend |
15 |
doing a prediction of the life-time. For normal usage, the number of |
16 |
possible write cycles should be sufficient. |

You should try sys-kernel/tuxonice-sources for suspend-to-disk. It |

preserves the cache as well. |

Ruggedized PC sitting on top of the rotor head of a helicopter, making |
36 |
videos of the blade movement. Works well, but the SATA connectors tend |
37 |
to fall off. ;-) |
