[systemd-devel] CopyBlocks= from initrd systemd-repart

[Renjaya Raga Zenta]

Hi,

I want to duplicate partition 1 and partition 2 using systemd-repart.
This is for SBC, I use mkosi to create the OS image.

By default, it needs 2 partitions

1. Boot partition: FAT32 used by 1st stage bootloader
2. Root partition: EXT4

This works fine.

Then I want to create "recovery mode", it needs 4 partition

1. Default Boot partition
2. Default Root partition
3. Secondary Boot partition
4. Secondary Root partition

Partition [3] should be copied from partition [1] and partition [4] should
be copied from partition [2].

I've configured the systemd-repart to run in initrd, I've also configured
udev rules to create symlink to device node:

1. /dev/gpt-part-boot -> /dev/nvme0n1p1
2. /dev/gpt-part-root -> /dev/nvme0n1p2 (mounted on /sysroot,
systemd-repart need this path because it's hardcoded in the source code)

But when I specify CopyBlocks=/dev/gpt-part-boot in the repart.d conf file,
it failed with this error message:
"Failed to open '/dev/gpt-part-boot': No such file or directory"

The systemd-repart failed in initrd, but then it will run again after
switch-root, and it works fine.

Any hints? I want the systemd-repart to run fine in initrd, not after
switch-root.

Thank you.
