Subject: alpha 5.0 BOOTMFS way too fat ..


I don't know if its the new toolchain, or if its general kernel bloat,
but a 5.0 BOOTMFS is nowhere near fitting onto a floppy:

% ls -lR /mnt/
total 1205
drwxr-xr-x 2 root wheel 512 Oct 25 21:37 boot/
-rw------- 1 root wheel 1228800 Oct 25 21:37 kernel.gz

/mnt/boot:
total 198
-rw-r--r-- 1 root wheel 640 Oct 25 21:37 device.hints
-r-xr-xr-x 1 root wheel 196128 Oct 25 21:37 loader*
-rw-r--r-- 1 root wheel 229 Oct 25 21:37 loader.rc

And the size of BOOTMFS is:

% ls -l kernel.gz
-rwxr-xr-x 1 gallatin wheel 1396562 Oct 27 16:17 kernel.gz*


I'm going to start trying to throw things over the side to lighten the
load, but I'm a little unsure how the driver floppy works.

May I jettison all drivers which are modules? Or do I need to keep
all possible scsi drivers required to boot the machine (in case we
booted from a SCSI CD)? Or does a different kernel get used for CD
boots? Or can /boot/loader make itself useful and load the drivers?

Thanks,

Drew

PS: My peeking at this in no way represents a commitment.
