I was hoping someone would answer this question completely, but it seems no one will. I can shed just a bit of light on the practices of a Prussian "boot camp," based on what I know of Baron Friedrich von Steuben.

von Steuben was a Prussian officer imported to the Continental Army during the American Revolution. He was brought over to serve in the army, and was appointed Inspector General. I don't know if it was the intended purpose of his commission, but he instituted a lot of major reforms in the American army.

Probably the biggest, or at least most obvious, was reforming the way camps were kept. Instead of allowing lax, free placement of tents and unrestricted excrement, he established the units in organized rows, with separate officer rows, and designated latrine areas. He also changed the way troops were trained and drilled.

He started drilling the men twice a day, and this included his cursing at them quite loudly, with an aid translating the profanity into English. He drilled troops on multiple levels, training them on their individual roles as well as their roles as part of a larger unit. He also drilled them in the use of the bayonet, which had been mostly neglected up until then. He pushed them from the green army they were into a more regular force.

Seeing as he was an officer of significant stature in the Prussian Army, well-seasoned and experienced in the ways of the soldier, it's safe to say that a lot of the reforms he brought over were taken from his experience in the Prussian Army under Fredrick the Great.

I have no idea how things were different for Napoleon's army. I'm afraid I can't help much there.
