# Disk Partitioning and Formatting
##
declare-flag install-system skip-formatting "" "Skip partitioning, formatting, and their post-commands. Instead, assume that all required disks/images/zpools are correctly partitioned/formatted, and simply (unlock/import and) mount them. This is useful to skip the destruktive part of the installation, but still do the (largely idempotent) part of copying and linking the current system generation and installing the bootloader -- i.e, repair an installation."
## Prepares the disks of the target system for the copying of files.
