[lfs-support] chroot into the temporary ...?
hi, It reads 'That is, we chroot into the temporary mini Linux system, ..' in Section6.1 of LFS7.4. but when i run 'sudo chroot /mnt/lfs', it returns 'chroot: failed to run command `/bin/bash': No such file or directory'. Of course /mnt/lfs/bin/bash not exists and then I tried 'sudo chroot /mnt/lfs/tools', it also 'chroot: failed to run command `/bin/bash': No such file or directory',but /mnt/lfs/tools/bin/bash exists. I really have no idea with the problem,maybe I have missed something in Ch5? Thanks in advance and sorry for my English. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

You didn't specify which program should chroot exec() after it chroots itself, so it did the default: tried to execute /bin/bash. Since there is no such program (/mnt/lfs/bin/bash in the root filesystem), it failed. To fix this, you should specify which program should be executed. Like this: chroot /mnt/lfs /tools/bin/bash But the full command is in Chapter 6.4. so look it up there. -- You don't need an AI for a robot uprising.

Also, a post in the thread LFSv7.4 stuck at section 6.9.1 gave me an idea about why you were unable to run `chroot /mnt/lfs/tools'. The bash that lives there requests the dynamic interpreter (run-time linker) /tools/lib/ld-whatever.so and that did not exist. You can verify this by adding a symbolic link `tools' to /mnt/lfs/tools which points to `..'. Like this (command run from /mnt/lfs/tools): ln -sv .. tools With this, you should be able to do `chroot /mnt/lfs/tools' without any problems. Just don't execute Section 6. with that setup because you will have A LOT of problems and a lot of thrashing.

Do we build sudo in chapter 5 (/tools) ? it returns 'chroot: failed to run command `/bin/bash': No such file or directory'. Of course /mnt/lfs/bin/bash not exists and then I tried 'sudo chroot /mnt/lfs/tools', it also 'chroot: failed to run command `/bin/bash': No such file or directory',but /mnt/lfs/tools/bin/bash exists. I really have no idea with the problem,maybe I have missed something in Ch5? Thanks in advance and sorry for my English. Apart from using sudo instead of su, why doesn't /bin/bash exist in /mnt/lfs ? If you are following the book, we create the /mnt/lfs/bin/bash symlink in section 6.6 - and we enter chroot *after* that, not in section 6.1. I'm sure that reading the book is *hard* for people who don't have English as a native language, but you seem to be making false assumptions about what the book says. ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
