Strictly from a gunsmiths' view, does it make much difference if my bolt is 2-lug, 3-lug or 9-lug? I know about short bolt throw and a scope clearance for the multi-lugs, but what else should I consider? I'm trying to choose between a Husq 1900 or Lakelander 375.
Does number of bolt lugs matter?

The total contact surface area is the important point, not the number of contacts.
You can't really compare a HVA 1640 and a Lakelander, both are different animals. One is a a true Mauser (model 1894 and 1898), Mauser derivative (HVA 1640) and the other one (Lakelander) is a '"modern" push feed action.
The Lakelander is made so the bolt lift throw will be shorter.
The Mauser 98 design introduced the rear lug (the 3rd one) for two reasons; to avoid action bending and act as a security if ever the receiver fails.
The two lugs Mauser is based on previous design, before the introduction of the high pressure rounds Model 1896 and earlier) (the 8X57 JS, was the first high pressure service round, introduced in 1905).
There is also the material difference; the early Mausers were made of low carbon steel (equivalent to SAE 1025 / 1035) while the post WWII derivatives usually have low alloy steel and then, most of the "modern" designs have Chrome-Moly steel.
The Lakelander was also made in match target configuration and was reknown for great accuracy (so were the Mausers). Both types of action need lapping of the bolt lugs to fit the receiver and I wouldn't worry too much about the lug contact (unless you want to make it a match grade rifle).
The final choice will depend on your own taste - a Mauser rifle or a "modern" push feed rifle.

He is actually referring to the Husqvarna 1900 action which if I remember correctly is actually a push feed and not a control feed mauser design.
I know nothing about the Lakelander rifles with the exception of their multiple lug design.
If you're not going to buy the Husqvarna, email me the link and I probably will. You can't go wrong with any Husqvarna action and especially not the 1900.

A nine lug action can be thought of as a three lug with the lugs split into threes. The contact area is tripled but the shear area is reduced. A nne lug would, in theory, be more resistant to deformation related to surface contact but less resistant to shearing force. Since, in both cases, both types are adequate (the three lug has sufficient contact, the nine lug has sufficient shear) it really does not matter. In the areas that matter, both will act the same. Bolt lift is greater with the three lug as compared with the two because the lift is shorter and the cocking cam steeper. The Weatherby counters this by making striker travel short and using a large diameter bolt. Generally speaking, I favour a two lug design for hunting use (hard to beat a Mauser for the purpose) but don't mind the three lug designs for target or varmint. Regards, Bill.
I recall seeing a 6 lug rifle that had failed because the owner tried to shoot a .308 in a .270 chamber. Point is that the front pair of lugs deeply cracked, the middle pair may have been cracked and the rear most pair were intact. That would only happen if the lugs did not equally match the recesses for them
