comment When does the Puppy linux security model make sense?
This answer is severely misleading. Malware does not have the "upper hand" if you're not logged in as root; it's at a disadvantage because it doesn't know the root password, and you (the user) do. Malware that manages to gain root privileges can completely subvert your system (including any "read-only" unionfs/aufs layers), and hide its presence so you'll never notice it's there (read about rootkits). If you run your whole login session as root, you're lacking an important security barrier that stands in the way of malware trying to do that.

comment tarring in parallel
"30, 40, or more quad-core processors" is not a workstation. It is a rather expensive server, or a low-end mainframe.

comment /dev/mapper in fdisk
Note that the Linux device mapper is used for other things besides LVM (such as dm-crypt disk encryption), so files in /dev/mapper aren't necessarily LVM logical volumes. But these ones look like they are. (They follow the naming convention that LVM uses.)

comment Debian 8 Jessie and NVIDIA drivers
FYI: you don't have to explicitly install a headers package and the DKMS package; just install nvidia-driver.

comment Reading the contents of an ELF file (programmatically)
Consider using the BFD library instead of implementing the ELF format yourself.

comment Recovering mismatched sectors in a RAID array
And yes, there are multiple versions of the data and no way to automatically determine which one is right. That's why the system doesn't try to repair the inconsistency automatically, but leaves it for a human to examine manually instead.

comment Recovering mismatched sectors in a RAID array
I wouldn't say it's "almost certainly" the checksum is wrong. If there's a discrepancy, it's probably because of corruption on one of the drives, and that could happen on any of them. (The alternative is a bug in the kernel code that calculates the checksum, but that code is well-tested and is the same for everyone, so there'd be mismatches on lots of arrays if that were the problem.)

comment Recovering mismatched sectors in a RAID array
There is alternate data, even with RAID5: it's what you get by ignoring the data from one of the disks (as if it had failed) and recomputing it based on the checksum and the other disks. It's even possible for that version of the data to be the "correct" one.

comment Restore EFI boot partition
Note that efibootmgr will only work if the system has been booted in EFI mode. Make sure your liveUSB supports EFI booting (it should have an EFI/boot/bootx64.efi file) and that you're actually booting it that way, not in legacy BIOS emulation mode.

comment When was my machine last touched?
Input device files' timestamps don't change when you move the mouse or press a key. The timestamp is part of the inode in the filesystem, which is unrelated to the driver that actually handles the input.
