While modern stacks force dual-stack, 6.8.2 allows clean separation. You can disable IPv6 entirely ( -4 flag) to save memory on a headless sensor node.
This often happens if a previous instance didn't close its PID file. You may need to manually delete /var/run/dhcpcd.pid . dhcpcd-6.8.2-armv7l
/usr/sbin/dhcpcd (stripped, ~85KB) /usr/lib/dhcpcd/dev/ (hook scripts: udev, openrc) /usr/share/dhcpcd/hooks/ (10-ipv4ll, 20-resolv.conf, 30-hostname) /etc/dhcpcd.conf (configuration)
This configuration should work reliably on most ARMv7l Linux distributions including Raspbian (legacy), Debian ARM, Arch Linux ARM, and custom Yocto/Buildroot systems. This often happens if a previous instance didn't
udhcpc wins for extreme minimalism, but dhcpcd-6.8.2 offers a better balance for devices needing IPv6 and predictable hooks.

This version belongs to a stable branch of dhcpcd released by developer Roy Marples. While modern Linux distributions may use versions 9.x or 10.x, version 6.8.2 remains highly prevalent in legacy systems, stable long-term support (LTS) distributions, and firmware environments where minimal resource footprints are required.
