Define sda as the smallest disk

[Rémy Dernat]

Ok, Thanks Thomas.

So, let's say I want to get a `$disklist` as an environment variable
for the setup-storage step (or '-D'), and this disklist is :
`$(newdisk_list=$(all_disks_by_size |sort -r | tr "\n" " ")`

How could I change my disk_config file to use this new list ? By
modifying `class/20-hw-detect.sh` (?); in the beginning of the
scripts, it says that the outputs of `*.sh` scripts are ignored ...

Thanks,
Rémy
