Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am trying to determine the date/time a file system was created. In particular, I am interested in ReiserFS and JFS. Initially, I considred using the ctime as an indicator, but it turned out not to be a reliable one. Then, I looked into the debugreiserfs and jfs_debugfs utilities, but they did not seem to be able to obtain that information.
Thank you for the link with information on ctime, mtime, and atime, which explains how it is not possible to tell when a file was created in Unix. However, I am trying to determine when a file system, not a file, was created.
I didn't see a date entry using "udevinfo -q all -n /dev/sda1" or using "sudo /usr/sbin/hwinfo --block". Perhaps some filesystems have a date stamp in the structure, but it would depend on the filesystem.
In ext3, I think the only date used is the last time checked.

ROTFL. Short read there, my apologies. ReiserFS and XFS I don't know about, but listing the superblock contents in ExtFS (debugfs, tune2fs) shows a "Filesystem created" entry. I doubt it's worth much though (as in "forensically irrefutable").
