210 core boot manager logic.
212 the way errors are handled is as such: if any particular step
213 cannot continue or unexpectibly fails, an exception is thrown.
214 in this case, the boot manager cannot continue running.
216 these step functions can also return a 0/1 depending on whether
217 or not it succeeded. In the case of steps like ConfirmInstallWithUser,
218 a 0 is returned and no exception is thrown if the user chose not
219 to confirm the install. The same goes with the CheckHardwareRequirements.
220 If requriements not met, but tests were succesfull, return 0.
222 for steps that run within the installer, they are expected to either
223 complete succesfully and return 1, or throw an execption.
225 For exact return values and expected operations, see the comments
226 at the top of each of the invididual step functions.
