Is there a vanilla kernel configuration? Ubuntu does not use LVM by default |

Linux compatible motherboard By and large, all of them is correct. There is the occasional board with fubar bios, but you're not going to find a comprehensive list anywhere. Best thing to do is pick a board and before you buy it, do some googling to see if anyone has complained about linux issues with it. |

Grub2 RAID /boot grub doesn't care about mdadm.conf; it reads the raid superblocks on the disk. You can't load a module from the disk when the module you are missing is one required to access the disk. Normally grub-install runs grub-probe which tells it that /boot is on a raid, so it builds raid module into the core image. This doesn't seem to be happening for you. |

Grub2 RAID /boot Grub2 prefers to use grub-probe to figure things out automagically instead of using a static device.map. It can boot just fine without a separate /boot partition also. That should also allow grub-mkconfig to automatically build the required raid modules into the core image. |

Creating a boot splash screen @amphetamachine that's because it isn't just a framebuffer program; it also can draw the splash screen via the X server to make for a smooth, flicker free shutdown splash. |

When is dd suitable for copying data? (or, when are read() and write() partial) @Gilles my mistake. I was thinking O_DIRECT, which does require block size and alignment. At any rate, dd is safe to use between two block devices without the fullblock flag ;) |

When is dd suitable for copying data? (or, when are read() and write() partial) @Gilles that is because cat uses the appropriate block size, as OrbWeaver noted in his answer. |

When is dd suitable for copying data? (or, when are read() and write() partial) @Gilles that sounds like a different issue entirely. You always have to use a multiple of the proper block size with block devices. I am pretty sure it is true of all unicies, and it is also true for Windows. |

How to get back sudo on Ubuntu? @Caleb I suppose there aren't that many. Obviously it depends on your distribution and what packages you have installed. On my Ubuntu server here at work, there appear to be two: /usr/bin/at owned by daemon.daemon, and /usr/sbin/uuidd owned by libuuid.libuuid. I'm pretty sure my desktop at home has several more. I suppose you are right; he didn't change the group ownership so things aren't nearly as bad. |

How to get back sudo on Ubuntu? @Caleb when you completely trash the permissions on an major chunk of the filesystem it is. He didn't just screw up sudo, presumably he forgot to mention in his post that he used -R ( otherwise it would have only changed the owner of the /usr directory itself and not sudo ). I also did describe how to reverse the process, but it is a very time consuming and painstaking task. |

Why does redirection (>) not work sometimes but appending (>>) does? That doesn't explain why append works, but truncate doesn't. If the writes are being denied, then append should still leave the file empty. |

PS/2 Keyboard & Mouse not working AFTER boot You need that option ON if you have a USB keyboard, or you won't be able to interact with grub. |
