Quotes around $@ (and ${arr[@]}) protect against word splitting and other substitutions, but still retain the list of argument members (and other array members).
In contrast, with $* and ${arr[*]} the quotes would enforce one string.

XT-CUSTOMIZE-IMAGE(8) Perl Programmers Reference Guide XT-CUSTOMIZE-IMAGE(8)NAME
xt-customize-image - Customize a freshly installed copy of GNU/Linux
SYNOPSIS
xt-customize-image [options]
Help Options:
--help Show this scripts help information.
--manual Read this scripts manual.
--version Show the version number and exit.
Debugging Options:
--verbose Be verbose in our execution.
Mandatory Options:
--location The location of the new installation
--dist The name of the distribution which has been installed.
All other options from xen-create-image, such as the new IP address(es)
to give to the new instance, will be passed as environmental variables.
NOTES
This script is invoked by xen-create-image after it has created a
fresh installation of Linux withing a temporary location.
This script will be invoked with a full copy of the arguments from
xen-create-image in its environment, along with several command line
arguments.
The command line arguments which are mandatory are:
--location - The temporary installation root of the new install
--dist - The distribution which has been installed.
HOOK SCRIPTS
The distribution name is used to locate an appropriate collection
of scripts, or hooks, to execute to do the actual customisation.
The hooks will each be executed with a single parameter which is
the directory path to the new instance. This argument is taken from
the --location option.
For the distribution named 'foo' the scripts will be loaded and
executed from '/usr/lib/xen-tools/foo.d'. Each executable will
be loaded and executed in sorted order.
