    Re: How do i change permissions for initramfs.conf

    Hi

    update-initramfs and mkinitramfs are both scripts.

    What they do is copy kernel modules, copy and run other scripts stored in other directories and hooks and a number of other things and then generate a compressed archive.

    This archive is the initrd file that becomes the early root filing system.

    Building cpio /boot/.....
    From what you posted earlier it seems to be getting far enough to generate the cpio (this is the archive).

    The files are copied into the directory /tmp and the cpio archive is generated and then rename in your /boot directory.

    From mkinitramfs

    Code:
    [ "${verbose}" = y ] && echo "Building cpio ${outfile} initramfs"
    (
    # work around lack of "set -o pipefail" for the following pipe:
    # cd "${DESTDIR}" && find . | cpio --quiet -R 0:0 -o -H newc | gzip >"${outfile}" || exit 1
    exec 3>&1
    eval `  
            # http://cfaj.freeshell.org/shell/cus-faq-2.html
            exec 4>&1 >&3 3>&-
            cd  "${DESTDIR}"
            {
                    find . 4>&-; echo "ec1=$?;" >&4
            } | {   
                    cpio --quiet -R 0:0 -o -H newc 4>&-; echo "ec2=$?;" >&4
            } | ${compress} >"${outfile}"
            echo "ec3=$?;" >&4
    `
    <snip>
    if [ -s "${__TMPCPIOGZ}" ]; then
            cat "${__TMPCPIOGZ}" >>"${outfile}" || exit 1
    fi
    I'm wondering if something odd is happening around here for some reason.

    Can you post the output of

    Code:
    ls /tmp/mkinitramfs_*
    Code:
    find /tmp/mkinitramfs_* ! -type d -exec ls -lh {} \; > ~/tmp.txt
    This second command will produce a file in your home directory called tmp.txt. Please post that as an attachment to your next post.

    Code:
    df -h
    Code:
    mount
    Code:
    which cpio
    Code:
    which lzma
    Code:
    sudo du -csh /tmp
    Code:
    ls /var/lib/initramfs-tools
    and finally

    Code:
    ls /boot/initrd*
    Let's see if we can work out what is going on.

    when i installed Lubuntu i had issues with mounting my harddrive and had to input a code to create the folder for it to beable to mount idk if their is any other folders i might happen to be missing wich might be the cause of all my woes
    Can you explain exactly what you did here please.

    Kind regards

    Code:
    lubuntu@lubuntu:~$ ls /tmp/mkinitramfs_*  
    ls: cannot access /tmp/mkinitramfs_*: No such file or directory 
    lubuntu@lubuntu:~$ find /tmp/mkinitramfs_* ! -type d -exec ls -lh {} \; > ~/tmp.txt

    Re: How do i change permissions for initramfs.conf

    the answer to your question highlighted by my quote is i used the mkdir command to make media/lubuntu (i think that was the one) and it fixed my problem with being unable to load any of the other drives i had dvd/1tb harddrive and various flash drives

    the drive i have my lubuntu operating system on is a 8gb kingston flashdrive

    Re: How do i change permissions for initramfs.conf

    now i have no clue exactly how to add a attachment to this forum matter but when i open with both abiword and leafpad
    tmp.txt comes up empty i dont know if im using the wrong program to read it or if its supposed to be empty or if by chance nothing is writing in it
    also that process that was running was hanging up until now till i accidentally clicked close tab instead of clicking copy to show the last line here
    -.- i feel like an idiot

    Re: How do i change permissions for initramfs.conf

    Darkishjace; I am back.

    This has progressed beyond my level of comprehension. I do not know what Matt is looking for exactly. But to ease your mind;

    lubuntu@lubuntu:~$ ls /tmp/mkinitramfs_*
    ls: cannot access /tmp/mkinitramfs_*: No such file or directory
    Those files do not exist either on my system and is the reason that tmp.txt is not written to.
    Await Matt's advise on if "mkinitramfs" files are removed upon completion of the scripts, or perhaps looking in the wrong directory ? IDK !
