Capture and deploy images of RaspberryPi SD Cards
By default, capture mode will shrink the last partition on the source drive to the minimum as reported by resize2fs(1), plus the value defined by --free (default: '500M'). This can be disabled by passing --no-shrink.
Filesystem and partition shrinking is only supported for ext4 filesystems for the time being. If an unsupported filesystem is encountered and --no-shrink was not specified, or the pyparted module cannot be imported, the resizing step will be skipped.
Deploy mode will simply write the specified source to the specified destination, no questions asked. Be sure you know what you're overwriting before going through with this.
- Python >= 3.5
- pyparted: For resizing partitions (optional)
- tqdm: For progress bar during copy (optional)
usage: imagerpi.py [-h] [-b SIZE] [-v] {capture,deploy} ...
Capture or Deploy images to sdcards
positional arguments:
{capture,deploy} sub-command help
capture capture help
deploy deploy help
optional arguments:
-h, --help show this help message and exit
-b SIZE, --buffer-size SIZE
Use a transfer buffer of size SIZE. Accepts suffixes
of B, K, M, or G.
-v, --verbose Enable verbose logging
usage: imagerpi.py capture [-h] [--no-copy] [--no-shrink] [-f SIZE] src dest
positional arguments:
src Source disk
dest Destination file
optional arguments:
-h, --help show this help message and exit
--no-copy Don't copy to dest.
--no-shrink Skip the filesystem shrinking step.
-f SIZE, --free SIZE Shrink last partition filesystem to include a minimum
of SIZE free space. Accepts suffixes of B, K, M, or G.
Example:
imagerpi.py capture /dev/mmcblk0 rpi.img
usage: imagerpi.py deploy [-h] src dest
positional arguments:
src Source file
dest Destination disk
optional arguments:
-h, --help show this help message and exit
Example:
imagerpi.py deploy rpi.img /dev/mmcblk0
- Add support for expanding the partition and filesystem on deploy
- Support compression (gz, xz, bzip2, et al.)
- Re-tool partition resizing operation to operate on the resulting image file instead of on the source device
- Add support for more filesystems
- Add more useful verbose messages
