[Bug 448413] [NEW] grub2 parses kernel parameters with $ as shell variables

[shemgp]

Public bug reported:

Binary package hint: grub2

The original kernel line in menu.lst was:

kernel          /boot/vmlinuz-2.6.31-13-generic
root=UUID=2d36e902-cd10-47a1-af4d-3eb85b8d97d6 ro
memmap=0x100000$0x38900000 splash

When I install grub-pc it asked me for kernel parameters and a placed
memmap=0x100000$0x38900000 as my ram has some bad blocks there. The
output of that line in grub.cfg was something like this:

        linux   /boot/vmlinuz-2.6.31-13-generic
root=UUID=2d36e902-cd10-47a1-af4d-3eb85b8d97d6 ro
memmap=0x100000/usr/sbin/update-grubx38900000  splash

which obviously won't let it boot. Edited /etc/default/grub to:

GRUB_CMDLINE_LINUX_DEFAULT="splash"
GRUB_CMDLINE_LINUX='memmap=0x100000\$0x38900000'

(note the single quote, otherwise it would have been GRUB_CMDLINE_LINUX="memmap=0x100000\\\$0x38900000")
So the output is now:

        linux   /boot/vmlinuz-2.6.31-13-generic
root=UUID=2d36e902-cd10-47a1-af4d-3eb85b8d97d6 ro
memmap=0x100000\$0x38900000  splash

and it boots successfully

I would expect that pasting the text as is would work like before
without resorting to backslashes.

I think this bug is related to #445952
