Indeed, all it needs is someone willing to do the work. Now if LVM had |

been written by Lennart Poettering, there would be a stampede of |
11 |
volunteers to do this, witness eudev. |

Of course it is, a RAID1 device is just a block device on which you can |

put any filesystem you like. RAID and LVM are complementary technologies |

that work well together, but neither needs the others (apart from the |
