#!/bin/bash
#
# Linux/MacOS X script to install rEFInd
#
# Usage:
#
# ./refind-install [options]
#
# options include:
# "--notesp" to install to the OS X root filesystem rather than to the ESP.
# This option is valid only under OS X.
# "--usedefault {devicefile}" to install as default
# (/EFI/BOOT/BOOTX64.EFI and similar) to the specified device
# (/dev/sdd1 or whatever) without registering with the NVRAM.
# "--ownhfs {devicefile}" to install to an HFS+ volume that's NOT currently
# an OS X boot volume. Valid only in OS X.
# "--root {dir}" to specify installation using the specified directory
# as the system's root
# "--alldrivers" to install all drivers along with regular files
# "--nodrivers" to suppress driver installation (default in Linux is
# driver used on /boot; --nodrivers is OS X default).
# "--shim {shimfile}" to install a shim.efi file for Secure Boot. Valid
# only under Linux.
# "--preloader" is synonymous with "--shim". Valid only under Linux.
# "--encryptkeys" password-protects the Secure Boot private key.
# "--localkeys" to re-sign x86-64 binaries with a locally-generated key.
# Valid only under Linux.
# "--keepname" to keep refind_x64.efi name as such even when using shim.
# Valid only under Linux.
# "--yes" to assume a "yes" response to all prompts

# Revision history:
#
# 0.13.3 -- Remove stray exit from CreateBootCsvFile()
# 0.13.2 -- Add installation of rEFInd Secure Boot key as MOK; if installing
# with Shim, add backup direct boot NVRAM option
# 0.12.0 -- Improve code to find ESPs; should help with NVMe drives. Also
# activate install and bootorder features when using --usedefault
# option.
# 0.11.5 -- Remove excessive slashes (/) from some filenames
# 0.11.4 -- Fixed generation of GUID when automount of ESP in use on Linux
# 0.11.3 -- Added support for ESP mounted at /efi under Linux
# 0.11.1 -- In Linux, be less aggressive about replacing existing NVRAM entries
# 0.11.0 -- Create BOOT.CSV file and option to encrypt SB private key
# 0.10.8 -- Enabled use of shimx64.efi.signed as Shim source file
# 0.10.7 -- Added mm{arch}.efi as equivalent of MokManager.efi
# 0.10.6 -- Improved identification of the root device under macOS.
# 0.10.5 -- More improvement to handling of disks (other than /dev/[sh]d? disks).
# 0.10.4 -- Improved handling of disks (other than /dev/[sh]d? disks).
# 0.10.2 -- Improved Secure Boot detection in Linux, fixed --usedefault in OS X,
# and fixed bug that could cause mountesp to be installed as a FILE
# called /usr/local/bin in OS X.
# 0.10.1 -- Improve extraction of default kernel options from /proc/cmdline.
# Add support for AMD64 (aka AARCH64, aa64) platform. Added
# warning when --alldrivers used without --usedefault.
# 0.10.0 -- Enable running under OS X's recovery system & add warning about
# SIP & brief instructions on how to deal with it if SIP is
# detected to be enabled. Also change way refind_linux.conf default
# options are found; use /proc/cmdline as base.
# 0.9.2 -- Added --keepname option.
# 0.8.7 -- Better detection of Secure Boot mode & fixed errors when copying
# Shim & MokManager files over themselves; fixed bug that caused
# inappropriate installation to EFI/BOOT/bootx64.efi
# 0.8.6 -- Fixed bugs that caused misidentification of ESP on disks with
# partition numbers over 10 on OS X and misidentification of mount
# point if already-mounted ESP had space in path.
# 0.8.5 -- Refinement/cleanup of new OS X ESP-as-default policy
# 0.8.4 -- OS X default changed to install to ESP under /EFI/BOOT
# 0.7.9 -- Fixed bug that caused errors if dmraid utility not installed
# 0.7.7 -- Fixed bug that created mangled refind_linux.conf file; added ability
# to locate and mount ESP on Linux, if it's not mounted
# 0.7.6 -- Added --ownhfs {device-filename} option
# 0.7.5 -- Fixed bug when installing to ESP on recent versions of OS X
# 0.7.2 -- Fixed code that could be confused by use of autofs to mount the ESP
# 0.7.0 -- Added support for the new Btrfs driver
# 0.6.12 -- Added support for PreLoader as well as for shim
# 0.6.11 -- Improvements in script's ability to handle directories with spaces
# in their names
# 0.6.9 -- Install gptsync on Macs
# 0.6.8 -- Bug fix: ESP scan now uses "uniq".
# 0.6.6 -- Bug fix: Upgrade drivers when installed to EFI/BOOT. Also enable
# copying shim.efi and MokManager.efi over themselves.
# 0.6.4 -- Copies ext2 driver rather than ext4 driver for ext2/3fs
# 0.6.3 -- Support for detecting rEFInd in EFI/BOOT and EFI/Microsoft/Boot
# directories & for installing to EFI/BOOT in BIOS mode
# 0.6.2-1 -- Added --yes option & tweaked key-copying for use with RPM install script
# 0.6.1 -- Added --root option; minor bug fixes
# 0.6.0 -- Changed --drivers to --alldrivers and added --nodrivers option;
# changed default driver installation behavior in Linux to install
# the driver needed to read /boot (if available)
# 0.5.1.2 -- Fixed bug that caused failure to generate refind_linux.conf file
# 0.5.1.1 -- Fixed bug that caused script failure under OS X
# 0.5.1 -- Added --shim & --localkeys options & create sample refind_linux.conf
# in /boot
# 0.5.0 -- Added --usedefault & --drivers options & changed "esp" option to "--esp"
# 0.4.5 -- Fixed check for rEFItBlesser in OS X
# 0.4.2 -- Added notice about BIOS-based OSes & made NVRAM changes in Linux smarter
# 0.4.1 -- Added check for rEFItBlesser in OS X
# 0.3.3.1 -- Fixed OS X 10.7 bug; also works as make target
# 0.3.2.1 -- Check for presence of source files; aborts if not present
# 0.3.2 -- Initial version
#
# Note: install.sh version numbers match those of the rEFInd package
# with which they first appeared.
