"File not found" Error on booting LFS 7.2
I completed doing LFS 7.2 as per the book. (Host system : Ubuntu 12.04)
For creating the configuration file ,I edited the /boot/grub/grub.cfg: --------------------------------- # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then set have_grubenv=true load_env fi set default="0" if [ "${prev_saved_entry}" ]; then set saved_entry="${prev_saved_entry}" save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z "${boot_once}" ]; then saved_entry="${chosen}" save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n "${have_grubenv}" ]; then if [ -z "${boot_once}" ]; then save_env recordfail; fi; fi } function load_video { insmod vbe insmod vga insmod video_bochs insmod video_cirrus } insmod part_msdos insmod ext2 set root='(hd0,msdos5)' search --no-floppy --fs-uuid --set=root 9287144e-03d3-42c0-8126-c5810f5532e7 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=auto load_video insmod gfxterm insmod part_msdos insmod ext2 set root='(hd0,msdos5)' search --no-floppy --fs-uuid --set=root 9287144e-03d3-42c0-8126-c5810f5532e7 set locale_dir=($root)/boot/grub/locale set lang=en_IN insmod gettext fi terminal_output gfxterm if [ "${recordfail}" = 1 ]; then set timeout=-1 else set timeout=10 fi ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### set menu_color_normal=white/black set menu_color_highlight=black/light-gray if background_color 44,0,30; then clear fi ### END /etc/grub.d/05_debian_theme ### ### BEGIN /etc/grub.d/10_linux ### function gfxmode { set gfxpayload="$1" if [ "$1" = "keep" ]; then set vt_handoff=vt.handoff=7 else set vt_handoff= fi } if [ ${recordfail} != 1 ]; then if [ -e ${prefix}/gfxblacklist.txt ]; then if hwmatch ${prefix}/gfxblacklist.txt 3; then if [ ${match} = 0 ]; then set linux_gfx_mode=keep else set linux_gfx_mode=text fi else set linux_gfx_mode=text fi else set linux_gfx_mode=keep fi else set linux_gfx_mode=text fi export linux_gfx_mode if [ "$linux_gfx_mode" != "text" ]; then load_video; fi menuentry 'Ubuntu, with Linux 3.2.0-23-generic-pae' --class ubuntu --class gnu-linux --class gnu --class os { recordfail gfxmode $linux_gfx_mode insmod gzio insmod part_msdos insmod ext2 set root='(hd0,msdos5)' search --no-floppy --fs-uuid --set=root 9287144e-03d3-42c0-8126-c5810f5532e7 linux /boot/vmlinuz-3.2.0-23-generic-pae root=UUID=9287144e-03d3-42c0-8126-c5810f5532e7 ro quiet splash $vt_handoff initrd /boot/initrd.img-3.2.0-23-generic-pae } menuentry 'Ubuntu, with Linux 3.2.0-23-generic-pae (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod gzio insmod part_msdos insmod ext2 set root='(hd0,msdos5)' search --no-floppy --fs-uuid --set=root 9287144e-03d3-42c0-8126-c5810f5532e7 echo 'Loading Linux 3.2.0-23-generic-pae ...' linux /boot/vmlinuz-3.2.0-23-generic-pae root=UUID=9287144e-03d3-42c0-8126-c5810f5532e7 ro recovery nomodeset echo 'Loading initial ramdisk ...' initrd /boot/initrd.img-3.2.0-23-generic-pae } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/20_linux_xen ### ### END /etc/grub.d/20_linux_xen ### ### BEGIN /etc/grub.d/20_memtest86+ ### menuentry "Memory test (memtest86+)" { insmod part_msdos insmod ext2 set root='(hd0,msdos5)' search --no-floppy --fs-uuid --set=root 9287144e-03d3-42c0-8126-c5810f5532e7 linux16 /boot/memtest86+.bin } menuentry "Memory test (memtest86+, serial console 115200)" { insmod part_msdos insmod ext2 set root='(hd0,msdos5)' search --no-floppy --fs-uuid --set=root 9287144e-03d3-42c0-8126-c5810f5532e7 linux16 /boot/memtest86+.bin console=ttyS0,115200n8 } ### END /etc/grub.d/20_memtest86+ ### ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os { insmod part_msdos insmod ntfs set root='(hd0,msdos1)' search --no-floppy --fs-uuid --set=root 4204FF7C04FF7171 chainloader +1 } ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### # This file provides an easy way to add custom menu entries.

If I understand you correctly then you added the lfs entry yourself.
Try, from your Ubuntu host as root user, to execute the update-grub command. This should find lfs and create an appropriate entry in grub.cfg. You might want to remove the entry you manually added first. |
Thanks.. I configured grub using update-grub. Now i restarted and selected the option for lfs from the grub menu. Then i got a black screen with the following error messages.
/proc /sys /devmount: unknown filesystem type 'devtmps' cp: cannot create directory '/dev/pts':Read-only file system ln: failed to create symbolic link '/dev/shm':Read-only file system checking file system...fsck.ext3:No such file or directory while trying to open /dev/sda4 |

- The first error (unknown filesystem type 'devtmps') could point to a missing kernel setting. Did you check/set the appropriate kernel options? - Are there any, earlier, message during boot indicating that partitions are mounted read-only? - From your host: What does the grub entry for LFS look like? - From your host: What is the output of fdisk -l and please point out which partition(s) you used to build LFS. - From LFS: Post the content of /etc/fstab BTW: Please put your script/data inside [code] ... [/code] tags. If you don't know how: LQ - BB Code List. |
Menu entry for lfs
------------------ Code:
### BEGIN /etc/grub.d/30_os-prober ### Output of fdisk -l from host ---------------------------- Code:

How can i check whether i set kernel options appropriately? |
The posted output seems to be OK.

--> File systems --> Pseudo filesystems --> Tmpfs entries Also have a look at this (the Note): 8.3. Linux-3.5.2 |
i cant find pseudo filesystems inside file systems.

Quote:
Code:
cd /path/to/linux-3.5.2 If these entries are not set then you need to rebuild the kernel as explained in chapter 8.3.1 |
I checked for pseudo filesystem inside both ubuntu file system and lfs.
Can u give me the exact path. |

(Re)do the steps in this chapter: 8.3. Linux-3.5.2 After executing the make menuconfig step you are presented with a menu. That's where you need to look. BTW: How did you create your initial kernel? I do hope you did do 8.3. Linux-3.5.2 and you did not copy a kernel from your host (which will _not_ work!!). |
Do i need to do anything before re doing chapter 8.3??

- Section 6.2.2, “Mounting and Populating /dev”, - Section 6.2.3, “Mounting Virtual Kernel File Systems”, - enter the chroot environment (as shown in 6.65). Now you are ready to redo 8.3.1 |
