Workaround for DELL Debian UEFI install that does not boot

Description

In most older (maybe also newer?) DELL workstations and thin clients, for example: DELL Precision T5810 and DELL Wyse 3040, Debian is not able to boot after installation is completed. This is because your workstation expects to boot from /EFI/BOOT/BOOTX64.EFI and it cannot find it. There is a way to manually configure this in Setup page and point to the correct grubx64.efi location, but for some reason it keeps trying to load from /EFI/BOOT/BOOTX64.EFI. The workaround provided here is basically renaming the grubx64.efi into BOOTX64.EFI and put it exactly where your workstation is expecting it.

The fix for "Gave up waiting for suspend/resume device" on Debian 12

For some reason, when the swap partition UUID changes, Debian takes much longer time to boot due to swap partition UUID mismatch in both /etc/fstab and /etc/initramfs-tools/conf.d/resume. This can happen when swap partition gets reformatted and assigned with new UUID.

Here is how to fix it:

  1. Get into root:
$ su
$ export PATH=/usr/sbin:/sbin:$PATH
