Undeterministic booster.alias causes different initramfs when it should be equal

```sh booster build booster.img booster build booster2.img diff booster.img booster2.img # they are different even though nothing has changed in the system booster unpack booster.img bunpack booster unpack booster2.img bunpack2 git diff bunpack bunpack2 ``` The diff shows that the only difference is the file `usr/lib/modules/booster.alias`. Sorting them makes the two images equal. Is there a reason for that? I would like to be able to just diff them to check if they match or not.
