+Booting
+=======
+
+One of the perhaps most frequent issues with configuring a Unix-like OS is
+setting up boot configuration correctly. The perceived difficulty mostly comes
+from not understanding the basic concepts behind booting.
+
+
+Firmware type
+-------------
+
+There are two firmware types: the older, BIOS, and newer, UEFI. Which one of the
+two is used depends on your system. If you can run
+
+ $ efibootmgr -v
+
+and it doesn't give an error message but a list of boot entries, then you have
+UEFI.
+
+
+Partition table type
+--------------------
+
+There are two partition table types: older, Master Boot Record (MBR), and newer,
+GUID Partition Table (GPT). UEFI systems usually use GPT, but other combinations
+are also possible.
+
+
+Boot loader
+-----------
+
+The program which carries out the initial stage of booting an OS is called a
+boot loader. This can be a program like GRUB, rEFInd, SYSLINUX, LILO and so on,
+on, or, in the case of Linux with UEFI, the kernel itself (EFISTUB).
+
+* With BIOS, bootloaders are written into the (master or volume) boot records of
+ disk partitions themselves (BIOS/MBR) or BIOS boot partitions (BIOS/GPT), and
+ this is where the system will look for them.
+
+* With UEFI/GPT, bootloaders are normal files on an EFI System Partition (ESP).
+ In order for the system to find them, their boot entries must be written to
+ EFI variables. This can be done by the program efibootmgr(8), but it can also
+ be done by the UEFI interface or an UEFI shell.
+
+
+Linux boot
+----------
+
+During the boot process, Linux executes the init program (usually /sbin/init)
+on the system root partition. This can be done in two ways:
+
+* By creating an initial root partition (initramfs) having a temporary init
+ program, which if needed handles loading the necessary kernel modules
+ (drivers) to access the root partition. This method supports advanced
+ partition selection, for example by their UUIDs or PARTUUIDs, and doesn't
+ require the support for filesystem type of the root partition to be compiled
+ in the kernel.
+
+* By specifying the root partition on the kernel command line (through a kernel
+ parameter), for example `root=/dev/sda2`. This is more minimal, as it doesn't
+ require initramfs, but prone to being unable to boot a system if the disk
+ configuration is changed, for example by plugging in a USB flash drive or
+ otherwise changing the order of the hard disks.
+
+
+Recommended setup in Galeb
+--------------------------
+
+The following is the basic recommended partition configuration in Galeb. It
+assumes an UEFI/GPT system.
+
+ Partition Mountpoint Filesystem Type Size
+ --------------------------------------------------------------
+ /dev/sda1 /boot vfat (32-bit) ~500MB
+ /dev/sda2 / ext4 Rest
+
+When configuring a boot entry, this means that the kernel command line will be
+
+ root=/dev/sda2
+
+and that the ESP is in /dev/sda1, mounted later during the boot process to
+/boot. This is where the kernel stub should go into, and will later be
+accessible from the booted system at /boot/vmlinuz.
+
+
+Creating a boot entry in efibootmgr
+-----------------------------------
+
+The necessary command line parameters will be briefly explained here. For more
+information, see `man 8 efibootmgr` and `efibootmgr -h`.
+
+ efibootmgr -c -d /dev/sda -l '\vmlinuz' -L 'Galeb EFISTUB' -p1 \
+ -u root=/dev/sda2
+
+-c Create a new boot entry.
+
+-d /dev/sda
+ Disk on which the root partition is (boot disk).
+
+-l '\vmlinuz'
+ Boot loader (our EFISTUB) is in the file vmlinuz on ESP. UEFI uses DOS
+ filesystem path separator, backslash (\), instead of a slash (/) used on
+ Unix-like systems.
+
+-L 'Galeb EFISTUB'
+ Label for the boot entry.
+
+-p1 ESP is the partition #1 on the boot disk (/dev/sda1).
+
+-u Treat the kernel command line as UCS-2.
+
+root=/dev/sda2
+ Kernel command line.
