Tried to reproduce problem with current installation ISO.
ubuntu at test:~$ uname -a
Linux test 3.16.0-14-generic #20-Ubuntu SMP Sat Sep 6 23:45:12 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux

1) case of installation using LVM without creating /home yet during
installation

=> no problem so far
and manually reproducing the supposed failing mkinitramfs using:
ubuntu at test:~$ sudo bash -x /etc/kernel/postinst.d/initramfs-tools 3.16.0-14-geeric /boot/vmlinux-3.16.0-14-generic > /tmp/L 2>&1
ubuntu at test:~$ cat /tmp/L
+ version=3.16.0-14-generic
+ bootopt=
+ '[' -z 3.16.0-14-generic ']'
+ '[' -n '' ']'
+ '[' -n /boot/vmlinux-3.16.0-14-generic ']'
++ dirname /boot/vmlinux-3.16.0-14-generic
+ bootdir=/boot
+ bootopt='-b /boot'
+ '[' -n '' ']'
+ INITRAMFS_TOOLS_KERNEL_HOOK=1
+ update-initramfs -c -t -k 3.16.0-14-generic -b /boot
update-initramfs: Generating /boot/initrd.img-3.16.0-14-generic
