fallback option doesn’t work

[Николай Сулейманов]

I’ve set up grub with the following config:


set default=tftp
set fallback=sysrcd32
set timeout=7

insmod gzio
insmod part_gpt
insmod ext2
set root='hd0,gpt3'
search --no-floppy --set=root --fs-uuid 12345678-1234-1234-1234-123456123456

menuentry 'TFTP boot' --id tftp {
    insmod net
    insmod tftp
    set net_default_server=10.9.8.7
    net_bootp
    linux (tftp)/rescue32 setkmap=us nonm scandelay=1
    initrd (tftp)/initram.igz
}

menuentry 'Custom SystemRescueCd x86' --id sysrcd32 {
        loopback loop /sysrcd.iso
        linux (loop)/isolinux/rescue32 isoloop=sysrcd.iso
        initrd (loop)/isolinux/initram.igz
}


But when grub fails at ‘tftp’ menuentry, is writes ‘Failed to boot both
default and fallback entries’. I’ve tried to replace the IDs with numbers 0
and 1 for default and fallback entries respectively, but that did not help.
If I change the iso file name to a non-existing one, then make ‘sysrc32’
the default and tftp the fallback, grub shows the same error anyway.
