how to protect sd card on rpi

[Zoran Kolic <zkolic%sbb.rs@localhost>]

After installing on raspberry pi, I found few articles,
how to help sd card to live longer. What is neccessary
to put in conf files for that?

I.e. to have in fstab:

   /dev/ld0a    /    ffs     rw,noatime,nodevmtime 1 1

Then to put into /etc/rc.conf:

  syslogd=NO
  manpagedb=NO
  savecore=NO
  virecover=NO
  fsck_flags="-P -p -y"

Also, how would apmd and powerd behave on rpi?
Best regards
