Now that I know how to use dracut I'm basically using it everywhere, |
| 15 |
even for VMs that have a single ext4 partition (where it really is a |
| 16 |
bit overkill). For the most part it is plug-and-play, and once you |
| 17 |
start getting multiple disks involved it adds a lot of robustness. |
| 18 |
Dracut can fsck your disks if you want, it can reliably mount the |
| 19 |
right root even with fairly confusing layouts, and it actually |
| 20 |
respects whatever is in /etc/fstab. It can also be told to mount |
| 21 |
anything you want before pivoting via an additional fstab (with the |
| 22 |
usual syntax). |

Sure, in theory it is one more thing that can go wrong, but I look at |
| 25 |
it more like one thing that can help get things to go right when they |
| 26 |
would otherwise go wrong. |

I'd encourage anybody who hasn't used it to at least get an |
| 29 |
understanding of it. It can make your life easier. |

There was a Lennart article about using the initramfs to do shutdown |
| 32 |
which was good reading. The concept is that you can cleanly unmount |
| 33 |
everything this way, and it also handles FUSE much better. |
