Problems installing grub files and kernel files under /boot since i
have followed the Coling instructions about moving to /usr, but i dont
know if these problems are related to this or due to other changes in

Since linuxmint doesnt have an installed to install the distro in an
encrypted LVM i have followed this howto
http://forums.linuxmint.com/viewtopic.php?f=141&t=71159  and i have
put linuxmint in an encrypted LVM and so far all went fine.

Some days ago i decided to replace Linuxmint by Ubuntu and i did
followed the same procedure and again all was running fine.

However today i have decided to replace Ubuntu 12.04  with Ubuntu
12.10 (quantal) and i have erased existent Ubuntu fs and i followed
the same procedure, but after running:

ubuntu]# unsquashfs -f -d /mnt/lm/ casper/filesystem.squashfs
Parallel unsquashfs: Using 4 processors
147918 inodes (153245 blocks) to write

                                      ]  27438/153245  17% cd
153245/153245 100%
created 94187 files
created 14237 directories
created 53613 symlinks
created 82 devices
created 0 fifos

it did NOT install vmlinux ubuntu kernel file in /boot like it used to
happen so far, and it also did not installed the grub files that used
to install and isntead now i have this:

boot]# ls -ls *
 824 -rw-r--r-- 1 root root  843468 Jul 23 21:15 abi-3.5.0-6-generic
 148 -rw-r--r-- 1 root root  147800 Jul 23 21:15 config-3.5.0-6-generic

total 4

as we can see theres no grub files inside /boot/grub and also theres
no initrd and vmlinux files to allow to boot into Ubuntu.

I even tested by installing again the Ubuntu release that was
successfully installed (before following Coling instructions about
moving to /usr) and now it happened exactly the same thing, no
vmlinux, initrc and no grub files.

Could anyone please clarify, or Colin ;) why now when running
"unsquashfs -f -d /mnt/lm/ casper/filesystem.squashfs" it doesnt
install kernel and grub files needed to boot the distro?

PS: i need to use this procedure even with Ubuntu since i want to have
in an encrypted LVM with cypher aes-xts*  because Ubuntu alternate CD
installer uses an older cypher.
        for linuxmint i really have no other option that use this
since it doesnt have an installer that allows to install the distro in
an encrypted partition (it only allow to encrypt home folder)
