# Mint the EBS-style /dev/disk/by-id symlink the upstream aws-ebs-csi-driver
# node plugin resolves, for hot-attached Viperblock virtio-blk volumes (vd*,
# serial = volume-id). This is the udev equivalent of the Alpine mdev rule
# wired by scripts/images/eks-node/setup.sh into /etc/mdev.conf.
#
# The shared helper /usr/local/sbin/mulga-ebs-byid (reused verbatim from
# scripts/images/eks-node/mulga-ebs-byid.sh) reads the device name from
# $MDEV or, if unset, $1 — so passing the kernel name via %k as the sole
# argument works without any udev-specific shim. udev already sets ACTION to
# add/remove, matching the values the helper's case statement expects.
# Already-attached devices at boot are coldplugged separately by
# mulga-ebs-byid.service; this rule only covers hotplug events.
