Same thing - chdir("/pub") works, but chdir("/") fails with ENOENT. 
Here's part of a sanitized truss:

3002:   chdir("/afs/PATH/ftp")             = 0
3002:   chroot("/afs/PATH/ftp")            = 0
3002:   chdir("/pub")                      = 0
3002:   chdir("/")                         Err#2 ENOENT
