Thanks Carol! Nothing like a Unix head to reinforce my point. :) It just rubs me raw sometimes how some of these engineers have these notions in there heads without any hands-on experience to prove what they've just always heard as Anti-MS chant. Most of them hardly haven't had their hands on a NT box, and hardly have in-depth experience on a Unix box.... they just think *nix is better than most 'cause they have a few years lite experience supporting limited Unix networks.
... and you put it so eloquently about the Cisco boxes too. They are nothing but boxes running a binary that expands in RAM to run like a boot-floppy kernel without "write" functionality to the OS. It's just the ASCII config file that has "xwrd" file rights.

Not sure on NT 3.51's version of NTFS, but if you say so, probably true. (not meant to be sarcastic, but sincere) As for the SQL database, depending if it had good rollback mechanisms to avoid corruption, it may or may not get corrupted, as you said. As for the unix systems, most of them use UFS, which is not a journalled file system. However, I do not know of many OSes or distributions that let you add in a journalled fs. One that comes to mind is linux with the reiserfs. (linux comes stock with ext2fs). (you can add in journalled file systems afterwards, one commercial unix in mind that comes stock and barrel with a journalled fs is the venerable Irix with it's XFS). Go ahead, pull the plug on him, he won't care. No fsck on startup. Just smooth rolling. If you note the pattern here, it is a function of the file system (or in the database's case, how it retains data and does integrity checks and if it has rollback recovery to avoid data loss or undo bad transactions). Not sure if I can give a definitive reason on why the cisco's do not fear such things. Probably because it is not usually writing data very often, and the data it writes is essentially a text file (NVRAM configurations). The "OS" in itself is a static flash file that never needs to be overwritten during normal runtime operation, only during upgrades. This is totally different on a fully blown OS that has crazy writes usually going on during operation. Or even if it did not, has a good reason to double check for file integrity. The Cisco router was meant to be more of an appliance like machine, so it's behavior makes sense, and so does it's obvious resistance to the occasional power plug pull.
