noflushd & hdparm
I finally have my laptop repaired. Yay! So I'm finally sorting out
how to make it use less power.
* I tracked down mobile-update and installed it.
* I set my noatime on all my filesystems.
* I installed noflushd, but now I'm wondering why.
My BIOS settings let me set spindown & sleep timeouts for the hard
drive, but they both only go up to 15 minutes. 15 mins of idle time
is fine for a spindown, but I want the sleep timeout longer, because
it takes a few seconds to wake up from that.
`hdparm -Y /dev/hda` will put the drive into a deep sleep, but I don't
see a way to have it happen automatically with a timeout.
`hdparm -S num /dev/hda` seems to set a timeout for spindown.
noflushd also seems to do a spindown, though the man page uses the
word "sleep". What's the purpose of noflushd then? Is it just for
drives that don't have idle timers built in? Is it redundant when
`hdparm -S` works? Is there a way to set a sleep timeout?
