-# EFI Sync
-
-Automatically install your kernel and initrd into the EFI when your Slackware system is updated.
-
-```
-Usage: ./efi-sync {install|watch}
-
-	- install: install the kernel and initrd into your EFI.
-	- watch: install on updates to your kernel
-
-```
-
-`efi-sync watch` watches your kernel path for updates.  Your EFI will be updated once
-one is detected and the package commands have completed.
-
-For systems using an initial ram disk (initrd), `efi-sync watch` watches
-/lib/modules and /lib/firmware for updates.  Your system is assumed to use one
-if '/etc/mkinitrd.conf' is present on start.  Once changes are detected, the
-initrd file is recreated using 'mkinitrd' and with the result installed into
-the EFI.
-
-You will need to manually install the initrd if it was recreated outside of
-this program.
-
-## Installation
-
-Run the following are root to install this command:
-```
-cp efi-sync /usr/local/sbin/efi-sync
-chown root:root /usr/local/sbin/efi-sync
-chmod +x /usr/local/sbin/efi-sync
-```
-
-The efi-sync will need to be integrated to start automatically on your system.
-
-## Configuration
-
-The command looks for configuration at /etc/efi-sync.conf.
-
-Here is an example with the default values:
-```
-# The kernel path to watch.
-KERNEL=/boot/vmlinuz
-# The path to the EFI kernel.
-EFI_KERNEL=/boot/efi/Slackware/vmlinuz
-# The path for the initial ram disk to install.
-INITRD=/boot/initrd.gz
-# The path to the EFI's initial ram disk.
-EFI_INITRD=/boot/efi/Slackware/initrd.gz
-```
-
-If you want the initial ram disk updated, ensure /etc/mkinitrd.conf exists and
-is configured correctly.
-
-### Testing
-
-To test everything is working correctly:
-
-```
-slackpkg -batch=on -default_answer=y upgrade --reinstall kernel-huge
-
-# You should confirm the recent update with this output.
-date -r /boot/efi/EFI/Slackware/vmlinuz
-```
-
-For initrd updates:
-```
-slackpkg -batch=on -default_answer=y upgrade --reinstall kernel-firmware
-
-# You should confirm the recent update with this output.
-date -r /boot/efi/EFI/Slackware/initrd.gz
-```
