Sorry if my post was understood wrong. I did mean to say the culprit was zfs, I was trying to state that a zfs-only installation makes the problem even worse. An UFS installation with many modules loaded by the loader do also take quite long to start. Right now, there are some cases where the modules must be loaded before the kernel. VirtualBox support for hostonly interfaces comes to my mind right now (vboxnetadp and vboxnetflt must be loaded before the kernel). Others like fuse are loaded by an rc script. So I would go with a kernel with all the support compiled in (even with opensolaris.ko and zfs.ko in my case) to boot and then load the rest of the modules with an rc script. I think this is a quite big move because it would mean removing the responsability of loading modules by the loader before the kernel. The loader would be resposible of loading the kernel and setting some configs that can only be set before booting. Hope I'm not saying anything incorrect. Sorry for the noise. Best regards, Gustau
