[mdlug] reiserfsck and badblocks

[Wojtak, Greg]

Just curious - why not ext2 instead of ext3?  Fewer moving parts, and /boot doesn't do a huge amount of transactions where journaling may be needed?

I'm curious because I always build my servers with ext2 on /boot and ext3 everywhere else.

	I use XFS extensively on my laptops that I have Linux loaded on, just 
because it's been a really good fit for them.

	That being said, I always set up /boot as ext3.  Firstly,  because of 
the issues with installing Grub or LILO mentioned above.  Secondarily, 
if I get into a real jam, /boot is then Linux-universally mountable from 
a boot CD or Live CD.  I've gotten jammed up trying to recover a 
non-booting system when /boot is XFS and not always easily mountable. 
As the partition has almost no activity against it after the boot 
process is done, it's not a big deal to have this happen.  / and the 
other filesystems are then set up XFS.
