Questions on creating RPM Package??

[Michael D. Setzer II]

Saw all the messages on Clonezilla, and brought up 
a question I'd ask a long time ago, and a new one.

Had asked about process to do an rpm package, 
and had gotten a suggestion to going a list on it, but 
turned out the list was dead, and had had no post 
for years, so that was a dead end.

Have been the maintainer of the G4L disk imaging 
program since 2004, and build it with Fedora as the 
build system. Have been able to run it from the CD, 
USB or even from grub2 menu by manually adding 
it. Doesn't have all the bells or options that 
Clonezilla has, but does things.

The grub option to add just required putting a 
kernel file and ramdisk.lzma file into boot directory 
and then using a 40_custom file.

# !/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu 
entries.  Simply type the
# menu entries you want to add after this comment.  Be 
careful not to change
# the 'exec tail' line above.
menuentry G4L {
	linux /bz5x12.13 root=/dev/ram0 telnetd=yes
	initrd /ramdisk.lzma
}

menuentry G4L_NOSMP {
	linux /bz5x12.13 root=/dev/ram0 telnetd=yes nosmp
	initrd /ramdisk.lzma
}

menuentry G4L_FailSafe {
	linux /bz5x12.13 root=/dev/ram0 noapic noacpi 
pnpbios=off acpi=off pci=noacpi nosmp
	initrd /ramdisk.lzma
}

That would then add options to the grub boot menu 
similar to how memtest worked to add option. It 
would load kernel image, and then g4l in ram to 
run. Looked at memtest, but note that they don't 
have an option with the EFI version, which was my 
new question with shift to more systems using that? 
Issues with creating signed kernels?

Wondering if there might be information or 
someone might know of a list or page?

Thanks.
