   3 # Linux/MacOS X script to install rEFInd
   4 #
   5 # Usage:
   6 #
   7 # ./install.sh [options]
   8 #
   9 # options include:
  10 #    "--esp" to install to the ESP rather than to the system's root
  11 #           filesystem. This is the default on Linux.
  12 #    "--usedefault {devicefile}" to install as default
  13 #           (/EFI/BOOT/BOOTX64.EFI and similar) to the specified device
  14 #           (/dev/sdd1 or whatever) without registering with the NVRAM.
  15 #    "--ownhfs {devicefile}" to install to an HFS+ volume that's NOT currently
  16 #           an OS X boot volume.
  17 #    "--root {dir}" to specify installation using the specified directory
  18 #           as the system's root
  19 #    "--alldrivers" to install all drivers along with regular files
  20 #    "--nodrivers" to suppress driver installation (default in Linux is
  21 #           driver used on /boot; --nodrivers is OS X default)
  22 #    "--shim {shimfile}" to install a shim.efi file for Secure Boot
  23 #    "--preloader" is synonymous with "--shim"
  24 #    "--localkeys" to re-sign x86-64 binaries with a locally-generated key
  25 #    "--yes" to assume a "yes" response to all prompts
  26 #
  27 # The "esp" option is valid only on Mac OS X; it causes
  28 # installation to the EFI System Partition (ESP) rather than
  29 # to the current OS X boot partition. Under Linux, this script
  30 # installs to the ESP by default.

  36 # Revision history:
  37 #
  38 # 0.7.7   -- Fixed bug that created mangled refind_linux.conf file; added ability
  39 #            to locate and mount ESP on Linux, if it's not mounted
  40 # 0.7.6   -- Added --ownhfs {device-filename} option
  41 # 0.7.5   -- Fixed bug when installing to ESP on recent versions of OS X
  42 # 0.7.2   -- Fixed code that could be confused by use of autofs to mount the ESP
  43 # 0.7.0   -- Added support for the new Btrfs driver
  44 # 0.6.12  -- Added support for PreLoader as well as for shim
  45 # 0.6.11  -- Improvements in script's ability to handle directories with spaces
  46 #            in their names
  47 # 0.6.9   -- Install gptsync on Macs
  48 # 0.6.8   -- Bug fix: ESP scan now uses "uniq".
  49 # 0.6.6   -- Bug fix: Upgrade drivers when installed to EFI/BOOT. Also enable
  50 #            copying shim.efi and MokManager.efi over themselves.
  51 # 0.6.4   -- Copies ext2 driver rather than ext4 driver for ext2/3fs
  52 # 0.6.3   -- Support for detecting rEFInd in EFI/BOOT and EFI/Microsoft/Boot
  53 #            directories & for installing to EFI/BOOT in BIOS mode
  54 # 0.6.2-1 -- Added --yes option & tweaked key-copying for use with RPM install script
  55 # 0.6.1   -- Added --root option; minor bug fixes
  56 # 0.6.0   -- Changed --drivers to --alldrivers and added --nodrivers option;
  57 #            changed default driver installation behavior in Linux to install
  58 #            the driver needed to read /boot (if available)
  59 # 0.5.1.2 -- Fixed bug that caused failure to generate refind_linux.conf file
  60 # 0.5.1.1 -- Fixed bug that caused script failure under OS X
  61 # 0.5.1   -- Added --shim & --localkeys options & create sample refind_linux.conf
  62 #            in /boot
  63 # 0.5.0   -- Added --usedefault & --drivers options & changed "esp" option to "--esp"
  64 # 0.4.5   -- Fixed check for rEFItBlesser in OS X
  65 # 0.4.2   -- Added notice about BIOS-based OSes & made NVRAM changes in Linux smarter
  66 # 0.4.1   -- Added check for rEFItBlesser in OS X
  67 # 0.3.3.1 -- Fixed OS X 10.7 bug; also works as make target
  68 # 0.3.2.1 -- Check for presence of source files; aborts if not present
  69 # 0.3.2   -- Initial version
  70 #
  71 # Note: install.sh version numbers match those of the rEFInd package
  72 # with which they first appeared.
