Puppy Linux Discussion Forum

Following the topic Difficulties installing EasyOS and some suggestions, I believe a script to automate the creation of an easyos folder containing the initrd, vmlinuz and easy.sfs files in a partition for installation on an internal hard drive a PC would be useful. The script would be launched from an Easy USB key.

I suggest that we (EasyOS users) collaborate to write it, as my bash knowledge and skills are limited

First ideas :

The script would take as argument the partition where we want to create the folder. The partition would be previously mounted (by EasyOS on the key)

$1 is the first (and only) argument, i.e. the chosen partition (e.g. sdb2)

Testing the existence of /mnt/$1:

PARTCHOSEN=$1
if [ ! -d "/mnt/PARTCHOSEN" ] ; then
  echo "The partition does not exist or it is not mounted"
  exit 1
fi

EDIT : Very bad, not work !

Checking that $1 is an ext4 partition:
??????

EDIT : the command lsblk -n -o FSTYPE /dev/PARTCHOSEN displays the filesystem type of /dev/$1

creation of the easyos folder:

mkdir /mnt/PARTCHOSEN/easyos
if [$? = 1 ] ; then
  exit
fi

EDIT : the character $ is missing in this code

copy the initrd and wmlinuz files to the easyos folder:

cp /mnt/wkg/initrd /mnt/PARTCHOSEN/easyos
cp /mnt/wkg/vmlinuz /mnt/PARTCHOSEN/easyos

EDIT : the character $ is missing in this code

copy of easy.sfs in easyos:

EDIT First try, Bad idea, it will generate an error if the version of EasyOS in use on the stick is not the last version installed.

(These commands are based on lines 1532 and following of the init script)

VERS="$(ls -l -d /mnt/wkg/releases/easy-* | rev | cut -f 1 -d '-' | rev)"
sortedVERS="$(echo "$VERS" | sort -t. -k 1,1n -k 2,2n -k 3,3n -k 4,4n)" #lowest to highest.
for LASTVERS in echo "$sortedVERS" | tail -n -1 | tr '\n' ' '`
  do
   cp /mnt/wkg/sfs/easyos/oe/kirstone/easy_${LASTVERS}_amd64.sfs /mnt/PARTCHOSEN/easys.sfs
  done

EDIT New try :

. /etc/lsb-release # retrieve the variable DISTRIB_RELEASE
cp /mnt/wkg/sfs/easyos/oe/kirstone/easy_${DISTRIB_RELEASE}_amd64.sfs /mnt/PARTCHOSEN/easys.sfs

EDIT : $PARTCHOSEN/easyos/ instead of PARTCHOSEN/

EDIT : it's easy.sfs, not easys.sfs

Thanks for your help

If I could offer a corollary where little to no effort would achieve this desire, would @BarryK (and others) be interested.

I have a solution that would NOT involve development work. But there must be some willingness to consider because it is NOT a development effort needing forum support. Further it would address/reduce most-all problems users encourter from the past, IMHO.

It has actually been done, per se. Kinda like; "in plain site (er... 'sight')".

If fact, I foresee the elements offered by the OP @Caramel as having relevance to this as well.

@Clarity , I didn't really understand

Another idea is to copy the easyos folder of the USB stick to the ext4 partition of the PC where EasyOS will be installed.

I have tested, it seems to work. But the encryption is lost (And, anecdotally, there will a partition integrity check at first boot)

Hi @Caramel
An ISO or IMG 'LIve" distro "is already a container to what you are asking to develop".

Your request is about "extraction". Extractions efforts are unnecessary for almost all distros on this forum'; from DOGs to PUPs.
Technology exist negating that need, if employed. Thus it eliminates the many-many problems of users attempting to extract info out for use elsewhere, the problems resulting from extracts, as well as those attempting to create new bootable media.

That's what I was offering to consider and is seen on the EASY forum here.

For the PUPs/DOGs, the systems behave exactly the same as an extraction-fixup you are asking to develop...except the extraction-fixup and future maintenance by some develop would be eliminated, too.

My first post was full of errors.

Probably no one cares, or you are too polite to tell me.

First script frugal_install_assistant.sh (it needs a lot of improvements)

#! /bin/bash

export TEXTDOMAIN=frugal_install_assistant.sh

yad --title=$(gettext 'Message') --text="/dev/$CHOSENPART $(gettext 'is not an ext4 partition')"
 echo "$(gettext '/dev/')$CHOSENPART $(gettext 'is not an ext4 partition')"
 exit
fi

 exit

yad --title=$(gettext 'Message') --text="/mnt/$CHOSENPART/$CHOSENREP $(gettext 'already exists')"

That's the way... 4 me, haha.

Essential.- EasyOS requires a partition with ext4 filesystem.

Nowadays, the easier to install, the more interesting for everybody.

Thanks for your help

Could you clarify what specific issues you're encountering with your current script? Are there particular steps that are causing errors or not behaving as expected?

After the numerous corrections in EDIT, the scripts (version Kirsktone/ version Scarthgap) work for me.

They could be used from an usb stick or from the internal drive for making a new install (frugal install with the same version of EasyOS as that used during installation)

Script easy-install ( for the EasyOS Scarthgap series):

This script helps to install EasyOS on a directory of an ext4 partition.
It must be used on a running EasyOS. It copies the 3 files (vmlinuz, initrd and esy.sfs) needed for an install to the directory choosen.
It asks for the name of the partition (examples: sda3, nvme0n1p2) and then the name of the choosen directory. (No folder or file with that name must already exist in the partition)

If the partition is not mounted, the script mount it ( Example /dev/sda3 is mounted in /mnt/sda3. If /dev/sda3 was already mounted elsewhere, the script will fail)

If the script was launched in a terminal,

(for example, if the script is in /files/downloads/, with the command

/files/downloads/install-easy 

)
it displays stanza to add to config files of a already installed bootloader grub4dos, grub2, limine or rEFInd.

Remane it install-easy and make it executable :

cd /files/downloads
mv install-easy.gz install-easy
chmod +x install-easy

OR

(actual compressed file)
Decompress it (For example by clicking on it and then click on the OK of the dialog window)
