systemd-repart

Declarative disk partition management

TLDR

Grow partitions automatically

$ systemd-repart

Dry run (view changes only)

$ systemd-repart --dry-run yes

Grow root to specific size

$ systemd-repart --size 10G --root /

SYNOPSIS

systemd-repart [OPTIONS] [DEVICE]

systemd-repart automatically grows and adds partitions based on configuration files in `/usr/lib/repart.d/` and `/etc/repart.d/`. It reads declarative partition definitions and applies them to the disk.This tool modifies partition tables but does not resize filesystems. Use `systemd-growfs` to extend filesystems after growing partitions.

PARAMETERS

--dry-run= BOOL

Show what would be done without applying changes

--size= SIZE

Target size for operations

--root= PATH

Operate on specified root directory

--definitions= PATH

Use configuration from specified directory

INSTALL

sudo apt install systemd-repart

CAVEATS

Only modifies partition tables, not filesystems. Configuration files define desired partition layout declaratively. Use dry-run mode to preview changes before applying. Primarily designed for image-based systems.

HISTORY

systemd-repart supports image-based OS deployment by enabling declarative partition management, allowing systems to automatically configure disk layout on first boot.
