I'd much appreciate some guidance with this. I'm trying to create a boot disk for Fedora Core4. I'm running mkbootdisk and it is failing with this exit...

+ echo 'Insert a disk in /dev/fd0. Any information on the disk will be lost.'
Insert a disk in /dev/fd0. Any information on the disk will be lost.
+ echo -n 'Press <Enter> to continue or ^C to abort: '
Press <Enter> to continue or ^C to abort: + read aline

+ realdev=/dev/fd0
++ /bin/mktemp /tmp/mkbootdisk.XXXXXX
+ device=/tmp/mkbootdisk.K22258
+ dd if=/dev/zero of=/tmp/mkbootdisk.K22258 bs=1024 count=1440
+ mountopts=loop
+ '[' -n '' ']'
+ mkdosfs -r 16 -I /tmp/mkbootdisk.K22258
/tmp/mkbootdisk.K22258: Permission denied
+ echo 'Failed to format /tmp/mkbootdisk.K22258'
Failed to format /tmp/mkbootdisk.K22258
+ rmdir /tmp/mkbootdisk.O22222
+ '[' -n /dev/fd0 ']'
+ rm -f /tmp/mkbootdisk.K22258
+ exit 1


I am running the script as root, and mktemp does succeed in creating the temp file with +rw for owner. Why would I be getting "permission denied"?

Thanks for the help!

I don't know about your script but, the 2.6 kernel ( FC4 has this ) is too big for a floppy disk.
You can put it on a cdrom ....

This might help, but I have to ask for some clarification. The purpose of this is to be able to restore my boot sector after I reinstall the dualboot OS.

The instructions I'm reading state that you have to point mkbootdisk to the version, but it doesn't seem that you're doing that here. Is this boot image going to be able to provide recovery of my existing boot sector?

Also after running it I don't seem to be left with much:

+ mkisofs -A 'Red Hat Linux Boot CD' -V 'Red Hat Linux Boot CD' -J -R -T -quiet -o boot.iso -b isolinux/i solinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /tmp/mkbootdisk.o23733
Unknown file type (unallocated) /tmp/mkbootdisk.o23733/.. - ignoring and continuing.
+ rm -rf /tmp/mkbootdisk.o23733
+ '[' -n '' ']'
+ '[' 0 -eq 1 ']'
+ exit 0

No ISO?

Thanks

The purpose of this command is to use mkbootdisk to create a bootable linux cdrom. This cdrom will boot into the system which you created it on.
This is the entire command.
The part with `uname -r` is a quick and ease way of pointing to the kernel version.

Once you run that command, an iso image is created called boot.iso .
Use that iso to create the cdrom. On my system, it would look like this....
