Write a system produced by Morph to a physical disk, or to a file that can
be used as a virtual disk. The target will be formatted as a single Btrfs
partition, with the system image written to a subvolume in /systems, and
other subvolumes created for /home, /opt, /root, /srv and /var.
When written to a physical drive, the drive can be used as the boot device
for a 'real' machine.
When written to a file, the file can be used independently of `morph` to
create virtual machines with KVM / libvirt, OpenStack or, after converting
it to VDI format, VirtualBox.
`morph deploy` will fail if the file specified by `location` already
exists.
If used in `morph upgrade`, the rootfs produced by 'morph build' is added
to the existing raw disk image or device as an additional btrfs sub-volume.
`morph upgrade` will fail if the file specified by `location` does not
exist, or is not a Baserock raw disk image. (Most users are unlikely to
need or use this functionality: it is useful mainly for developers working
on the Baserock tools.)
Parameters:
* location: the pathname of the disk image to be created/upgraded, or the
path to the physical device.
* VERSION_LABEL=label - should contain only alpha-numeric
characters and the '-' (hyphen) character. Mandatory if being used with
`morph update`
* INITRAMFS_PATH=path: the location of an initramfs for the bootloader to
tell Linux to use, rather than booting the rootfs directly.
(See `morph help deploy` for details of how to pass parameters to write
extensions)
