# Usage: bee-install <device> [logfile]

# logfile — optional path to write progress log (default: /tmp/bee-install.log)

Usage: bee-install <device> [logfile]
Installs the live system to a local disk (WIPES the target).
device Target block device, e.g. /dev/sda or /dev/nvme0n1
Must be a hard disk or NVMe — NOT a CD-ROM (/dev/sr*)
logfile Optional path for progress log (default: /tmp/bee-install.log)
Examples:
bee-install /dev/sda
bee-install /dev/nvme0n1
bee-install /dev/sdb /tmp/my-install.log
WARNING: ALL DATA ON <device> WILL BE ERASED.
Layout (UEFI): GPT — partition 1: EFI 512MB vfat, partition 2: root ext4
Layout (BIOS): MBR — partition 1: root ext4
