OS installation

  1. Prepare bootable Rocky Linux 9 USB using: 
    dd if=Rocky-9.0-x86_64-dvd.iso of=/dev/sdd
    

    sync
    Assumes umount /dev/sdd* is done and that /dev/sdd does not has any critical data before itself.
    This can ideally be done via Rocky 9.x Ventoy to have multiple installers on a single USB
  2. Ideally boot using UEFI (F12) key so that Windows partition and boot manager are left untouched
  3. During installation select
    1. In Installation destination
      1. Select all available disks and custom partioning
      2. For partitioning dont format /boot/efi (100MB) and mount it on /boot/efi. Tyepe if "EFI System partiton"
      3. Reformat (or Create new ) root (/) and swap and mount them as / (50GB) and swap (16 GB) respectively
      4. If there is existing /mnt/data1 then mount it on same path without reformat. Or create a lvm /mnt/data1 with all other remaining available space.
      5. Dont mount /mnt/cdrive yet. We may need to install ntfs-3g before we mount that. It is possible only when C-drive is not encrypted using bitlocker.
    2. In Software Selection go with "Server with GUI". Select "Graphical Administration Tools" and "System Tools"
    3. Select Asia/Kolkata timezone and optional am/pm format, even if time is reported wrong. After installation correct time is automatically shown.
    4. Disable kdump and security profile
    5. On "Network & Host Name" set hostname as barjatiyarklp(N)
    6. Set root and user accounts. Allow root ssh login with password. Make the user administrator.
    7. Begin installation
  4. After installation setup repositories: 
    dnf -y install https://mirrors.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-9.noarch.rpm
    

    dnf -y install rpmfusion-free-release-tainted
    

    dnf -y install rpmfusion-nonfree-release-tainted


Initial configuration

  1. Boot and login and skip tour
  2. Allow user to run sudo without password: 
    visudo
    Enable sudo access without password for wheel group
  3. Ensure that "Location services" are turned off
  4. In "Screen Lock" Disable automatic screen lock and set Blank Screen Delay to never.
  5. In "Power" enable "Show Battery Percentage"
  6. Disable SELinux (setenforce 0, /etc/sysconfig/selinux SELINUX=disabled)
  7. Edit /etc/hosts and add appropriate entries:
    • 172.31.1.164 rekallcm1
    • Other relevant /etc/hosts entries from other machines
  8. Configure history retention Storing date / time along with commands in history
  9. (Optionally) Configure alias for checking battery status CentOS 7.x check laptop battery information
  10. (Optionally) Logout and change the display to "Standard (X11 Display manager)" from "Standard (Wayland)" and login again
  11. (Optionally) Edit /etc/yum.conf and configure keepcache=1
  12. Full update system using 'dnf -y update --skip-broken --nobest'
  13. dnf -y install epel-release
  14. dnf -y install screen tmux
  15. Start a tmux or screen session for rest of the tasks
  16. CentOS 8.x gnome prevent grouping of similar windows with alt-tab
  17. Optionally Go to settings -> Online accounts and add google account with 5TB storage
  18. Install "Passwords and Keys" Gnome application


/mnt/data1 files

First setup /mnt/data1 encrypted via Rocky 9.x Encrypt LVM logical volume before filesystem setup

If it is a new laptop with empty /mnt/data1 then copy following from old machine to new:

  • /mnt/data1/large_files/operating_systems
  • /mnt/data1/plain_folders
  • /mnt/data1/setup
  • /mnt/data1/windows_setup
  • /mnt/data1/workspace/ excluding owncloud folder

Sample command: 

  rsync -a --exclude 'lost+found' --exclude 'owncloud' root@<remote-ip>:/mnt/data1/ /mnt/data1/

If existing laptop is formatted while keeping /mnt/data1 intact then perhaps we only need to empty the owncloud folder under /mnt/data1/workspace

Also if existing laptop already had encryption enabled then we need to still do /etc/crypttab and /etc/fstab based mounting of encrypted partition in new OS also.
