Re: ext3 problem, help please!
Hi, initrd is touchy subject.:) I like it. I agree with dman's points
basically with some reservation.
Also some stock kernels (not all) comes ext2 as a part of kernel while
ext3 as a module. With current initrd script, root is mounted as ext2.
See bug at http://bugs.debian.org/135537

I use stock debian kernel-image or local version with minimum change.
So even local one uses initrd.
This way, I do not need to recompile kernel when playing with hardware
configuration such as frame-buffer, CDRW (ide-scsi) or ext2. Much more
flexible with modules.
I remember including too many things as a part of kernel at one point
which ended me up with some error due to its size.
There are few functionalities such as ACPI and magic SYSReq keys which
was left out of stock kernel. This way, I can still use stock kernel
without reconfiguring system when new one comes out and I can wait
recompile it until I have time

Yes. There is a prompt during boot time which gives you chance to do
insmod. This is good if you add SCSI etc.

Shameless plug :)
There is debian specific ext3 upgrade description.
