uvol: add new package
uvol is a wrapper-script which allows automated handling of storage volumes. uvol currently comes with backend support for LVM2 and UBI, covering practically all options for storage large enough to be managed (NAND, SPI-NAND, eMMC, SATA, NVME, virtio-blk, ...).

'uvol' is tool to automate storage volume handling on embedded
|
||||
devices in a generic way.
|
||||
Also install the 'autopart' package to easily make use of 'uvol' on
|
||||
block-storage based devices.
|
||||
|
||||
Examples:
|
||||
uvol create example_volume_1 256MiB rw
|
||||
uvol up example_volume_1
|
||||
uvol device example_volume_1
|
||||
|
||||
uvol create example_volume_2 9812733 ro
|
||||
cat example_volume_2.squashfs | uvol write example_volume_2 9812733
|
||||
uvol up example_volume_2
|

uvol device example_volume_2
