I have:
$ cat /etc/release
SVN-20120311 (7.1)
$ grub-install --version
grub-install (GRUB) 1.99
# blkid | grep LFS
/dev/sda1: LABEL="LFS71" UUID="54f684bc-5a56-4a05-8a93-37dd108c617e"
TYPE="ext4"
One section og grub.cfg:
menuentry 'GNU/Linux, with Linux 3.5.3-lfs' --class gnu-linux --class gnu
--class os {
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root 54f684bc-5a56-4a05-8a93-37dd108c617e
echo 'Loading Linux 3.5.3-lfs ...'
linux /boot/vmlinuz-3.5.3-lfs root=/dev/sda1 ro
}
In another machine:
$ cat /etc/release
SVN-20120311 (7.1)
$ grub-install --version
grub-install (GRUB) 1.99
# blkid | grep -i LFS
/dev/sda3: LABEL="LFS" UUID="0a76e206-bd43-4ebf-b54a-75c9c1cf4267" TYPE="ext4"
menuentry "GNU/Linux, with Linux 3.5.3-NG-pae (on /dev/sda3)" --class gnu-linux
--class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd0,msdos3)'
search --no-floppy --fs-uuid --set=root 0a76e206-bd43-4ebf-b54a-75c9c1cf4267
linux /boot/vmlinuz-3.5.3-NG-pae root=/dev/sda3 ro
}
Although the search not being useful, according to the editors, here, I
did not bother to delete the respective lines.
What is grub version?
