I am planning to deploy the amd64/pure64 version of Debian on a new system. However while investigating the netinst images at http://debian-amd64.alioth.debian.org/debian-installer/daily/netboot/ I noticed that the initrd misses something I would need in there: the 3ware 3w-xxxx.ko and/or 3w-9xxx.ko kernel modules.
Would it be possible to add those to the initrd? It seems that the 3ware 9000 series is pretty popular among AMD64 users.
The netboot images have no disk or cdrom drivers at all and don't need any. They are ment for pure network installs and download exra modules over the net.
Hm? I'm sorry I don't really understand what you say. Or at least I'm not certain I do. How do the netboot images work, if they don't have any cdrom drivers?
1) If they don't access the cdrom itself (apart from loading the initrd
perhaps), why do the images include any packages at all? If what you
said is correct, those packages can't be accessed, so they would be
a waste of storage.
2) How do they store whatever they load of the net? In a ramdisc?
I must admit I never dissected any netboot image before, and I obviously can't try the amd64 image yet, since I don't have the hardware yet. But I am eager to learn, so what is the mechanism behind the netboot images? What do they load to which destination during each step of the boot and installation process?
If I get the idea correctly, this is what happens basically: 1) kernel and initrd get loaded 2) modules from initrd are loaded as far as they are needed to get additional software (packages, modules) from the net. 3) the installer starts and loads any modules needed to do the install (SCSI/SATA/PATA/whatever drivers primarily) from the net 4) destination media get's partitioned and mounted 5) the real installation starts
Is that more or less right?
