Well, plus all running services/daemons unless you take them down
after chrooting and bring them up again within the chroot.
This can be a life saver. I have my portage tree on box A while box B
NFS mounts it. At one stage, NFS versions of A and B got so out of
sync, B couldn't NFS mount /usr/portage any more. A LiveCD with an
NFS version matching (well, at least fitting) the one on box A was my
path to salvation. ;-)
