Combining passes during Vista setup ?

Hi guys,

if I understand this correctly after reading the Vista unattended guides one would have to add at least three passes (each requiring a reboot) in addition to the normal phases of a vista setup if one would want to add applications and regtweaks (specialise pass + audit mode pass) and copy the userprofile over to the default user (generalize). This would make 5 reboots during an unattended installation if I counted this correctly.

Is this really necessary ? Can´t you combine phases so that things happen in one phase instead of two ? For instance when installing applications one has to first add commands to the specialise phase in order to add environment variables that are then needed in the audit phase. Then, to copy the user profile into the default user profile a generalize phase is seemingly necessary. Why not simply do all of those things in one phase ??

Maybe that´s a dumb question but it is very different from a Windows XP setup and the number of reboots necessary is really a nuisance in Vista.

Thanks,

Alex
