Package: grub-common
Version: 2.04-3
Severity: normal
Tags: patch
Dear Maintainer,
The grub helper script for linux menu entries does not escape strings relevant to paths &c. This can lead to problems if a system is
installed on a btrfs subvolume that contains whitespaces in its name,
resulting in a entry like this:
menuentry 'siduction 2014.1.0 indiansummer (kde) GNU/Linux' --class siduction --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-acfcc995-6784-4033-ac1e-182c11772bef' {
load_video
insmod gzio
if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
insmod part_gpt
insmod btrfs
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root acfcc995-6784-4033-ac1e-182c11772bef
else
search --no-floppy --fs-uuid --set=root acfcc995-6784-4033-ac1e-182c11772bef
fi
echo 'Loading Linux 5.2.11-towo.2-siduction-amd64 ...'
linux /Debian Root/boot/vmlinuz-5.2.11-towo.2-siduction-amd64 root=UUID=acfcc995-6784-4033-ac1e-182c11772bef ro rootflags=subvol=Debian Root quiet
echo 'Loading initial ramdisk ...'
initrd /Debian Root/boot/initrd.img-5.2.11-towo.2-siduction-amd64
}
This can be easily fixed by escaping the lines
linux ${rel_dirname}/${basename}.efi.signed root=${linux_root_device_thisversion} ro ${args}
linux ${rel_dirname}/${basename} root=${linux_root_device_thisversion} ro ${args}
to
linux '${rel_dirname}/${basename}.efi.signed' root=${linux_root_device_thisversion} ro ${args}
linux '${rel_dirname}/${basename}' root=${linux_root_device_thisversion} ro ${args}
and the line
initrd $(echo $initrd_path)
to
initrd '$(echo $initrd_path)'
and the line
GRUB_CMDLINE_LINUX="rootflags=subvol=${rootsubvol} ${GRUB_CMDLINE_LINUX}"
to
GRUB_CMDLINE_LINUX="rootflags=subvol='${rootsubvol}' ${GRUB_CMDLINE_LINUX}"
Regards,
Valentin Petzel
