I would like to modify the ubuntu 20.04 installation iso to include (vlc, audacious,mc,rar,unrar, spanish support,etc), remove (totem,rhythmbox,english support, etc) and upgrade packages. Use Cubic but change the permissions of various system directories. Leading to a security risk. For example /etc and /usr have 777 I need customize installer becouse the computers I want installer don't have network acces I need customize installer because I live in Cuba and is very difficult access online repository from anywhere also the connections are too slow for example in this PC (256kbs).
I've recently tried to create a custom Ubuntu installer iso from the Ubuntu 16.04 64 bit server installer, with the aim of editing the /etc/apt/sources.list
file. I unpacked the iso, expanded the squashfs filesystem, chrooted into it and edited the /etc/apt/sources.list
file. Then I repacked the filesystem, regenerated the md5sum and generated a new iso image. This all seemed to work and the iso image can boot and be used to install Ubuntu.
While doing this I noticed that the sources.list file I was editing was much smaller than a normal sources file. It only contained the 'main' component for the archive.ubuntu.com mirror, and similar entries for the security and updates mirrors. When I installed from the new iso, the /etc/apt/sources.list
file was the full file I'm used to seeing, complete with all repository components such as universe etc. The sources file also appears to be based on my location, as all entries used the gb.archive.ubuntu url.
I assume that I'd only edited the file used within the installation process, which didn't affect the actual sources file in the final installation.
How is the final version of the /etc/apt/sources.list
file generated when the operating system is installed, and can I affect this without recompiling apt?
I was wondering how can i install boinc at /home folder. I have an ssd for root and /home on a hdd. Since boinc does lot of write/read i would like to avoid installing it on my ssd (which i already did via muon). I have trim enabled and working but i would still like to get it on my hdd. Do i have to uninstall/reinstall boinc and if yes how do i install it at /home folder? Thanks in advance :)
I'd like to copy my exact setup from my computer at work to my computer at home. I'm trying to figure out how to go about doing that. So far I've figured this much out.
On the source computer run
dpkg --get-selections > installed-software
and backup the installed-software file
Backup /etc/apt/sources.list Backup /usr/share/applications/ to save all my custom Quicklists Backup /etc/fstab to save all my network mounts Backup /usr/share/themes/ to save the customization I've done to my themes I'm also going to backup my entire HOME directory.
Once I get to the destination computer I'm going to first do just a fresh install of 11.10 Then I'll copy over my HOME directory, /etc/apt/sources.list, /usr/share/appications, /etc/fstab and /usr/share/themes/
Then I'm going to run
dpkg --set-selections < installed-software
Followed by
dselect
That should install all of my apps for me.
I'm wondering if there's a way/need to backup dconf and gconf settings from the source computer? I guess that's my ultimate question. I'd also like any notes on anything else that might need backed up as well before I undertake this project. I hope this post is legit, I figured other people would be interested in knowing this process and I don't see any other questions that seem to really document this on here.
I'd also like to further this project and have each computer routinely backup all the necessary files so that both computer are basically identical at all times. That's stage 2 though...
I installed Kubuntu on a spare work computer and I am now configuring it for the standard user's needs. My goal is to install it on 4 rarely used PCs for them to play around with, and maybe put it on their own computer some time.
There is some stuff I want to be the same on every computer (e.g. Thunderbird instead of Evolution, the mail-in and mail-out server of the users), and stuff that needs to be customized on every machine, like hostname, a different user on each PC...
Also, the computers have differently sized hard drives. Will a 10GB image pushed onto a 300GB hard drive "break" the file system so it seems to be only 10GB big? Sorry, this is hard to explain in English.
Does anyone know of a way to generate a custom image of a full hard disk sda1
as /
, sda2
as swap
and sda3
as /home
? Also, if I just burn the .iso on a DVD I won't be able to boot and push the image on the HDD, right?
