You can't assume that. eg:
[root@ts root]# cat /etc/passwd | grep :/:
nobody:x:99:99:Nobody:/:/sbin/nologin
rpc:x:32:32:Portmapper RPC user:/:/bin/false
[root@ts root]#

summer@Dolphin:~$ echo $HOME
/home/summer
summer@Dolphin:~$ HOME=/ sh -c 'echo $HOME'
/
summer@Dolphin:~$ HOME=/$HOME sh -c 'echo $HOME'
//home/summer
summer@Dolphin:~$

If you mean something different from all of these, please clarify.
