ftpd chdir() while root

Seems to me that ftpd does chdir(homedir) while root, before setting
UID/GID to the user logging in. This creates difficulties if the home
directory is on another machine via NFS with root_squash, and I guess
is a security issue as in some cases you may get a current directory
that would otherwise be inaccessible.
