[Server] minimal vm install - keyboard layout not saved

[Popov Kapov]

When installing ubuntu server 15.10 as a minimal VM install, and using a keyboard layout different than US selected in the process, (currently using FR:oss), the installer doesn't save the change in the initramfs.
After the reboot at end of the installation process, the console login is reverted and keeps defaulting to the US qwerty layout, instead of the selected layout (should be FR)

it's worth noting :
- some files seems to be missing from a standard installation in /usr/share/initramfs-tools/scripts/*

- the following commands work, but don't survive a reboot :
sudo apt-get install console-common => azerty layout ok (select full list, fr/azerty)
sudo dpkg-reconfigure keyboard-configuration => ok (same)

Doing a "update-initramfs -u", followed by a reboot => back to qwerty/us layout at the logon prompt.

There is no error message, neither on screen or in any log, aside the syslog installer complaining about gzip missing (cf attachement).

- Everything is as default from a fresh install, the problem is present immediatly after the installation is complete.

For the record, this bug appeared with 15.04 and still not yet fixed. The only improvement is the installer using the keyboard layout for the install, while previously it complety ignored the selection and kept the US layout in any mode (minimal VM or full), for the whole installation process
