Hi everyone,

Have you tried to install Ventoy on an USB Flash drive? It can also be installed on (internal!) HDD/SSD. Please read:
2404BE-12-Refracta-Snapshot-10.4.1-User-Manual.pdf,
section:
#J. Using a swap partition on your USB stick with Ventoy

For more info, read the HowTo (in .md) on my SourceForge site (in DEV state).

WKR, Odie

The issue "Compression error for type [cpio archive]" is solved in Refracta Snapshot 10.4.1.

Debian also returns "YourUserName is not in the sudoers file", when issuing the sudo command.
To add YourUserName to /[etc/sudoers] perform the following actions:

> open Terminal
    

su - root

    > type the password of the root account
    

visudo

    > press the [arrow-down] button
    > go to section "# User privilege specification"
    > add a line beneath "root...ALL": "{YourUserName} ALL=(ALL:ALL) ALL", e.g.:
    

obi7kenobi ALL=(ALL:ALL) ALL

    > press [ctrl]+[O] (write out)

    message: "file name to write: /etc/sudoers.tmp"
    This file name is OK. The actual file is [/etc/sudoers].

    > press <enter>
    > press [ctrl+[X] to exit the editing mode

Dear fsmithred, The new [/bin/refractasnapshot-gui] version 10.4.0 does not solve my problem.

Problem:
"Compression error for type [cpio archive]" when extracting initrd.img-6.5.0-26-generic.

Investigation:
1. [xed /var/log/refractasnapshot.log]:

Replace "xed" with your favorite editor.

++ file -L /boot/initrd.img-6.5.0-26-generic
++ egrep -o 'Zstandard compressed|gzip compressed|XZ compressed|cpio archive'
+ initrd_compression='cpio archive'
+ '[' '!' 'cpio archive' ']'
+ popd
+ '[' 'cpio archive' == 'Zstandard compressed' ']'
+ '[' 'cpio archive' == 'gzip compressed' ']'
+ '[' 'cpio archive' == 'XZ compressed' ']'
+ popd
+ echo 'Initrd is extracted'
+ edit_initrd
+ pushd /tmp/extracted
+ '[' -f conf/conf.d/cryptroot ']'
+ '[' -f cryptroot/crypttab ']'
+ '[' -f conf/conf.d/resume ']'
+ '[' -f conf/conf.d/zz-resume-auto ']'
+ popd
+ rebuild_initrd
+ pushd /tmp/extracted
+ '[' 'cpio archive' == 'gzip compressed' ']'
+ '[' 'cpio archive' == 'XZ compressed' ']'
+ '[' 'cpio archive' == 'Zstandard compressed' ']'
+ echo 'Compression error for type [cpio archive]...'
+ exit 1

2. The command [file -L /boot/initrd.img-6.5.0-26-generic] returns "ASCII cpio archive (SVR4 with no CRC)". This information is flaw.

Cause:
Linux Mint 21.3 uses an initrd.img file of type "initramfs" as of kernel version 5.15.0-94, and cannot be extracted/rebuilded using the cpio command.

Solution:
Use unmkinitramfs to extract- and mkinitramfs to rebuild the initrd file.

(tested on kernel: vmlinuz-6.5.0-26-generic, initrd: initrd.img-6.5.0-26-generic, distro: Linux Mint 21.3, desktop: Cinnamon 6.0.4, base: Ubuntu 22.04)

with:

extract_initrd () {
# Customized {FillInCurrentDateTime} by {FillInYourName} 

    rm -rf /tmp/extracted
    mkdir /tmp/extracted
    pushd /tmp/extracted	
    
    unmkinitramfs "$initrd_image" "/tmp/extracted"
    
    if [ $? -eq 0 ]; then 
        echo "SUCCESS: unmkinitramfs has successfully extracted the original Initrd to /tmp/extracted" 
    else 
        echo "ERROR: unmkinitramfs has failed to extract the original Initrd"
        echo "Script execution terminated"
        rm -rf /tmp/extracted
        exit 1 
    fi
    popd
}

> search for: "rebuild_initrd ()"

> replace:

to:    }
with:

rebuild_initrd () {
# Customized {FillInCurrentDateTime} by {FillInYourName}

    pushd /tmp/extracted
    mkinitramfs -c gzip -o ${work_dir}/iso/live/${initrd_image##*/}

    if [ $? -eq 0 ]; then 
        echo "SUCCESS: mkinitramfs has successfully rebuilded the custom Initrd" 
    else 
        echo "ERROR: mkinitramfs has failed to rebuild the custom Initrd"
        echo "Script execution terminated"
        rm -rf /tmp/extracted
        exit 1 
    fi
    popd
    rm -rf /tmp/extracted
}

Notice that the container is compressed using the gzip algorithm. I guess this solution can also help Ubuntu users.

Nonetheless, still very happy using Refracta Snapshot!
