def plugin_loaded()

After this, proceed to install the Syslinux boot code (mbr.bin or gptmbr.bin) to the Master Boot Record 440-byte boot code region

For a partitionless install, there is no need to install the Syslinux boot code to the MBR.

run_scripts()

# For boot time only; this is overridden at build time in hook-functions

No guarantees are made as to the order in which the different scripts are executed unless the prereqs are setup in the script. Please notice that PREREQ is only honored inside a single directory. So first the scripts in /usr/share/initramfs-tools are ordered according to their PREREQ values and executed. Then all scripts in /etc/initramfs-tools are ordered according to their PREREQ values and executed.

1) <hex_major><hex_minor> device number in hexadecimal represents itself * no leading 0x, for example b302. * 2) /dev/nfs represents Root_NFS (0xff) * 3) /dev/<disk_name> represents the device number of disk * 4) /dev/<disk_name><decimal> represents the device number * of partition - device number of disk plus the partition number * 5) /dev/<disk_name>p<decimal> - same as the above, that form is * used when disk name of partitioned disk ends on a digit. * 6) PARTUUID=00112233-4455-6677-8899-AABBCCDDEEFF representing the * unique id of a partition if the partition table provides it. * The UUID may be either an EFI/GPT UUID, or refer to an MSDOS * partition using the format SSSSSSSS-PP, where SSSSSSSS is a zero- * filled hex representation of the 32-bit "NT disk signature", and PP * is a zero-filled hex representation of the 1-based partition number. * 7) PARTUUID=<UUID>/PARTNROFF=<int> to select a partition in relation to * a partition with a known unique id. * 8) <major>:<minor> major and minor number of the device separated by * a colon.
