No, the home directory gets built in /etc/profile, using HOME.
Take a look.
HOME is setup be Cygwin, from the Windows HOME or from /etc/passwd,
see the FAQ.

There are three things here.
- One is a quoting problem in /etc/profile that causes the cp error.
- The second is the "mkpassd_l_d" group name. That is the name invented
by mkgroup, as it can't access the domain controller to get the real group
name. Simply edit /etc/group and change the group to anything you fancy.
- The third is the home directory, which is setup by mkpasswd -c from
HOMEDRIVE/HOMEPATH. Simply edit /etc/passwd and set it as you like, 
or redo "mkpasswd -l -c -p /home > /etc/passwd ".

So basically you are all set.
