Near the end of the chapter, the book recommends users of the ext3 filesystem to use hdparm to test if a disk is able to accept the barrier=1 mount feature.
This is a good suggestion, but it doesn't say anything about hdparm beyond that. The current instructions as written imply that the user already has hdparm installed which might confuse new users. I'm sure most people will be able to figure it out, but for clarity I think it would be worth mentioning that instructions for hdparm are in BLFS so people don't assume hdparm is part of their system already. Something simple would suffice, such as a note like this after the instructions themselves: Note: Build instructions for the hdparm package can be found in the BLFS book.
