I?m working on a thing = I never tried before. I did some googling but I don?t think I haven?t found= any correlated to this. <= FONT face=3D"Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" size=3D= 2> The situation is pretty simple: I?m conf= iguring a FreeBSD (6.1) server to boot from a SAN thru a QLogic 2340 Fiber = Channel card. This in general is not a problem as I already have another wo= rking machine with this solution. Now for a couple of reason not= related to FreeBSD this new machine won?t yet =5Fboot=5F from the SAN itself but at the same time ha= ve all the system installed on the SAN. What I need to do is have a boot de= vice that loads the bootsector, the kernel and then starts everything else = from the disk in SAN. <= SPAN lang=3DEN-GB style=3D"FONT-SIZE: 10pt; FONT-FAMILY: Arial">= I thought about accomplishing this with a B= OOT-CD that starts up the kernel and then from the fstab loads the /, /etc,= /usr and so on from the SAN. Now my question is this: how do th= e kernel know where to search the fstab (considered that the fstab says whe= re to find the /etc)? I mean: I suppose I have to put on the CDROM an exact= /etc/fstab for that installation?? Or this could be avoided? Also because = I may need to edit the fstab for the machine without having to reburn the C= D? so what? Or maybe the kernel can actually just be read from the CD and t= hen everything else from the ( SAN | local ) drive? Am I missing something?= I?m yet in the make buildworld buildkernel stage so maybe when m= aking the make distribution to create the ISO everything will appear cleare= r to me but right now something it?s not really clear. = I hope the= scenario is clear. Any suggestion? Any link to any kind of docum= entation? Thank you very much. Andrea Brancatelli =
