what partitions to mount during upgrade ?

["Blair, Charles E III" <c-blair@illinois.edu>]

   I am an unsophisticated user who has finally gotten
around to upgrading a desktop from wheezy to jessie.  I am
trying to follow the instructions in the "release notes,"
but don't really know what I'm doing.

   My current question is to clarify the instructions about
mounting partitions at the beginning of section 4.4.  I
think I am supposed to issue as superuser the commands

mount -o remount,rw /
mount -o remount,rw /usr

Are there any other mount commands to issue before
apt-get upgrade ?  How do I find out?  I don't think
it matters, but this is a dual-boot using grub with
windows as the other system.
