# RFS flists (firmware manifest naming)
# FIRMWARE_TAG controls firmware flist manifest naming for reproducible builds.
# - If set, firmware manifest becomes: firmware-$FIRMWARE_TAG.fl
# - If unset, the build embeds firmware-latest.fl, while standalone pack may default to date-based naming.
# Examples:
# FIRMWARE_TAG="20250908"
# FIRMWARE_TAG="v1"
#FIRMWARE_TAG="latest"

# Branding and customization guard (default off)
# Set to "true" to enable Zero-OS branding and passwordless root in initramfs.
# Both variables are accepted; ZEROOS_BRANDING takes precedence if both set.
ZEROOS_BRANDING="true"
ZEROOS_REBRANDING="true"

# Root account configuration
# Provide either ZEROOS_ROOT_PASSWORD_HASH (preferred, SHA-512 crypt) or ZEROOS_ROOT_PASSWORD (plain, will be hashed during build)
# Legacy variable names also supported: ROOT_PASSWORD_HASH / ROOT_PASSWORD
# Passwordless root is the default for branded builds when no password is provided.
ZEROOS_PASSWORDLESS_ROOT="true"
# ZEROOS_ROOT_PASSWORD_HASH=""    # optional, preferred when setting a password
# ZEROOS_ROOT_PASSWORD=""         # optional, dev-only; if set, overrides passwordless
