Hi All,
I have working (Perl) code to combine 2 input files into a single output file using the join function that works to a point, but has the following limitations:

SYSTEMD-GPT-AUTO-GENERATOR(8) systemd-gpt-auto-generator SYSTEMD-GPT-AUTO-GENERATOR(8)NAME
systemd-gpt-auto-generator - Generator for automatically discovering and mounting root, /home and /srv partitions, as well as discovering
and enabling swap partitions, based on GPT partition type GUIDs.
SYNOPSIS
/lib/systemd/system-generators/systemd-gpt-auto-generator
DESCRIPTION
systemd-gpt-auto-generator is a unit generator that automatically discovers root, /home, /srv and swap partitions and creates mount and
swap units for them, based on the partition type GUIDs of GUID partition tables (GPT). It implements the Discoverable Partitions
Specification[1]. Note that this generator has no effect on non-GPT systems, or where the directories under the mount points are already
non-empty. Also, on systems where the units are explicitly configured (for example, listed in fstab(5)), the units this generator creates
are overridden, but additional implicit dependencies might be created.
This generator will only look for root partitions on the same physical disk the EFI System Partition (ESP) is located on. It will only look
for the other partitions on the same physical disk the root file system is located on. These partitions will not be searched on systems
where the root file system is distributed on multiple disks, for example via btrfs RAID.
systemd-gpt-auto-generator is useful for centralizing file system configuration in the partition table and making manual configuration in
/etc/fstab or suchlike unnecessary.
This generator looks for the partitions based on their partition type GUID. The following partition type GUIDs are identified:

| | | mounted to /boot or /efi, see below. |
+-------------------------------------+--------------------------------+--------------------------------------+
The /home and /srv partitions may be encrypted in LUKS format. In this case, a device mapper device is set up under the names
/dev/mapper/home and /dev/mapper/srv. Note that this might create conflicts if the same partition is listed in /etc/crypttab with a
different device mapper device name.
Mount and automount units for the EFI System Partition (ESP) are generated on EFI systems. The ESP is mounted to /boot, unless a mount
point directory /efi exists, in which case it is mounted there. Since this generator creates an automount unit, the mount will only be
activated on-demand, when accessed. On systems where /boot (or /efi if it exists) is an explicitly configured mount (for example, listed in
fstab(5)) or where the /boot (or /efi) mount point is non-empty, no mount units are generated.
When using this generator in conjunction with btrfs file systems, make sure to set the correct default subvolumes on them, using btrfs
subvolume set-default.
systemd-gpt-auto-generator implements systemd.generator(7).
