While not strictly a XFS question, I hope since you folks have hacked
all this together you might be know of an option I have not
considered and have hopefully come across the problem before.

I have installed a RH 7.1 server with your XFS patches on it which works
wonderfully (thank you so much!). I made it into a kickstart server and
to my delight XFS installs perfectly over it. My problem is thus: my kickstart
%post script normally does a mkbootdisk as part of the post initial install
process, reboots the machine, and then a script which runs the first time
the machine comes back up twiddles the floppy back to a kickstart disk.

>From the looks of it, the XFS kernel patches take up a lot of space. The
stock RH 7.1 kernel comes in around 781K, while the patched XFS kernel comes
in around 1.3M, which barely would fit onto a floppy by itself, never mind
the initrd file.

>From bootnet.img, I tried to just change the syslinux.cfg file, but that goes 
straight into
the installer regardless. Back in 6.0, you could do this but I guess it no 
longer
works that way.

mkbootdisk makes a vfat filesystem, which IIRC does not allow you to use
"super" floppies >1.44M. Just checked, it'll let me mkbootdisk with device 
/dev/fd0u1600, but won't boot from it :-(

A requirement is that this work with both SCSI and IDE systems, so I'm wary
of rolling my own kernel and initrd.

Any ideas very much appreciated.
