I'm creating a necromancer wizard player character and searching for the most optimal amount of undead to control. I searched for the lore of the monsters, and found that Ghasts tend to be leaders in packs of ghouls. But I couldn't find how a Ghast does that, or how many can it can maintain in order.
So that makes me wonder. Can a controlled ghast be the boss of an uncontrolled pack of ghouls? And if he can, how many could it command?
That could significantly boost the amount of undead my necromancer could control by indirect means:
The idea I have is to create ghouls using my 6th level spell slot, and maintain the superior slots for a ghast, who will introduce the newcomers to the pack, so when the next day comes, they already are in a group controlled be the more powerful undead, who will in turn be controlled by me.

You are talking about NPC interactions
When it comes to a ghast's command of ghouls, it isn't some magical effect. It is simply the ghast's greater power and "cunning"...
This is similar to how a powerful bugbear might inspire a collection of lowly goblins. Since it is simply a matter of character interaction, it will be ultimately up to the GM how this works.
Ghouls are not particularly intelligent creatures, so if they are already in league with a ghast they may become tag-alongs as long as you keep them well-fed. Whether or not your ghast can command a new group of ghouls will largely depend on what exactly motivates the ghouls in a particular situation.
