quick notes

these have a 32 bit efi, but a 64 bit cpu, so typical linux distros get confused, additionally, the video card is a bit unsupported.

at the grub menu, select the “compatibility” option for mit, press “c” and send these commands:

insmod efi_gop
insmod efi_uga
insmod font
insmod gfxterm
set gfxmode=1680x1050
terminal_output gfxterm

then go back to the grub menu by pressing “esc” and add these to your kernel params

nomodeset radeon.modeset=0

then presse “f10” to boot into the installer

rsync -aAXH –numeric-ids –info=progress2 /var/ /mnt/newvar/

This command is a classic way to perform a full system-level migration of a directory while keeping every bit of metadata intact.

Here is the breakdown of each option:

• -a (Archive mode): This is a shortcut for several flags. It preserves symbolic links, permissions, modification times, groups, and owners. It also ensures the copy is recursive.
• -A (ACLs): Preserves Access Control Lists. This ensures that any specific user/group permissions set outside of standard Linux “rwx” permissions are carried over.
• -X (Extended Attributes): Preserves “xattrs” (like security labels or user-defined metadata). This is vital for systems using SELinux.
• -H (Hard links): Tells rsync to look for hard links in the source and recreate them in the destination. Without this, rsync would copy each hard link as a separate, full file, wasting disk space.
• --numeric-ids: Tells rsync to transfer the UID/GID numbers as they are, rather than trying to map them by username/group name. This is crucial when copying to a drive that will be used by a different OS or a “Live” environment where the user IDs might not match yet.
• --info=progress2: Provides a modern, single-line progress bar for the entire transfer (showing total percentage and speed) rather than listing every single file as it goes.

I want all files inside the directory to get 777 permissions when they are created inside this directory.
