The function now stores parameters into var kernel_parameters. The
new function does not set the kernel name (vmlinuz). This must now be
done in the bootloader configuration code.

why the [[ ]]?
It is recommended to use [[ ]] in bash when we are not trying to right a
POSIX compliant script. However, [[ ]] implies -n by default.
Therefore, I shortened the code as so: [[ "${_label}" ]] &&

this branch seems useless in this function. the variable $subdir is not used
here?
I was thinking that we could do this assignment here and use it for both
the grub and Syslinux menu generation code. However, now looking at it,
$subdir would have to be global variable. Since the check is simple and
can be condensed to one line of code [[ -z "$bootdev" ]] && local
subdir="/boot" it would make more sense to add the assigment in
generate_grub_menulst and generate_syslinux_menu. That code isn't very
likely to change or get modified.
-----------------------------------
local raw_device crypt_device lv_device
What do you think of making these variables local? As far as I can tell
they are not used anywhere else in the code.

messed up indentation here.
Woops, fixed. IIRC that is the way it was originally.
I will reply to this email, with a patch of these changes so you can see
the code that has changed.
