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