Details:
Grub2 strips quotes from kernel command line arguments:
My linux command line looks like:
linux /boot/vmlinuz-2.6.32-rc3 root=/dev/sda3 ro acpi_osi="!Windows
2006" nmi_watchdog=0 reboot=pci
but when booting the kernel I get the following message:
0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-2.6.32-rc3
root=/dev/sda3 ro acpi_osi=!Windows 2006 nmi_watchdog=0 reboot=pci
indicating that the quotes were stripped.
So I believed that maybe in this message but internally the arguments are
right, but indeed, they are hosed. I added printk to the kernel params.c
parsing routine and what do I get:
[ 0.000000] DDDD param=BOOT_IMAGE, val=.../boot/vmlinuz-2.6.32-rc3...
[ 0.000000] DDDD param=root, val=.../dev/sda3...
[ 0.000000] DDDD param=ro, val=...<NULL>...
[ 0.000000] DDDD param=acpi_osi, val=...!Windows...
[ 0.000000] DDDD param=2006, val=...<NULL>...
[ 0.000000] DDDD param=nmi_watchdog, val=...0...
[ 0.000000] DDDD param=reboot, val=...pci...
which clearly shows that grub is doing something *completely* wrong here.
The only way to fix that is to boot into grub, edit the command line and add
change it to \" \", and then boot with Ctrl-x.
Changing the original boot.cfg cmd line to any variant of \"...\", or
\\"...\\", etc etc does not work.
That is a serious regression against grub1 and lilo, both of them did it
right!
