It should be a common thing, I am not all that sure about the offerings on linux. But the openbsd project offers full disk encryption and a bootloader that handles it well.
Actually, this may be a common mistake I make. On openbsd if the project says something works it will usually be simple to set up and have a nice documentation. So I then think "Well if the tiny openbsd project can do it, it must be this easy everywhere" which is not true at all. The two cases that come to mind were booting off a softraid volume(hopefully this one is fixed) and setting up a netflow source. both of which proved to be trivial on openbsd and a huge pain in the ass on linux. The other common mistake I make is to use the openbsd man pages(they are just better) on linux and wonder why nothing is working right.
