# post_build.sh - Common post-build script for Raspberry Pi
#
# Called by Buildroot after assembling the target rootfs.
# Arguments:
#   $1 = path to the target rootfs directory (e.g., output/target)
#
# Environment:
#   BR2_EXTERNAL_RPI_COMMON_PATH = path to this external tree
#
# Use this script for:
#   - Fixing file permissions
#   - Creating symlinks
#   - Generating config files that depend on build-time variables
#   - Stripping unnecessary files from the rootfs
#
# Do NOT use this for:
#   - Installing packages (use rootfs overlay or a package .mk instead)
#   - Modifying files outside $1

# Example: ensure /etc/hostname exists with a default value

# Example: remove unnecessary documentation to save space
rm -rf "${TARGET_DIR}/usr/share/man"
