Package: grub-pc Version: 1.96+20080203-1 Severity: critical Justification: breaks the whole system
The If-statement 00_header writes to grub.cfg is malformed, and causes grub2
to get stuck in an infinite loop of syntax errors.
This code breaks the system:
if font (hd0,5)/usr/share/grub/unicode.pff ; then
set gfxmode=1024x768
insmod gfxterm
insmod vbe
terminal gfxterm
fi
My fixed grub.cfg is below. I fixed 00_header the same way:
font (hd0,5)/usr/share/grub/unicode.pff
set gfxmode=1024x768
insmod gfxterm
insmod vbe
terminal gfxterm
