# Hardware device configuration. Hammerhead's SMF runs this unconditionally
# (upstream illumos only runs it on reconfigure boots, which leaves PCI
# NICs unattached on fresh deploys); we follow Hammerhead's convention.
/usr/sbin/devfsadm
# Load minor_perm + device_policy (/etc/security/device_policy) into the
# kernel. WITHOUT this, the kernel keeps its restrictive built-in default
# (DEFAULT read_priv_set=all / write_priv_set=all), so a NON-root process
# can't even open() /dev/null or /dev/zero — open() returns EACCES. That
# breaks the non-root (zygaena) build (perl/OCaml/reefc all redirect to
# /dev/null) and any non-root program. `devfsadm -P` is the only devfsadm
# mode that loads these tables (illumos did it in SMF's devices-local
# method; the zyginit port dropped it). Absolute path per the zyginit
# boot-script convention.
/usr/sbin/devfsadm -P
# Clear the first-boot reconfigure flag. hh-deploy drops /reconfigure so a
# fresh deploy does a full device enumeration on its first boot; the kernel
# reads the flag at boot and performs a reconfigure boot (rebuilding the
# device tree, ~15s to write /etc/devices/pci_unitaddr_persistent). illumos's
# devices-local method removes the flag afterwards — the zyginit port dropped
# that step, so WITHOUT this every boot reconfigures: slow boot + a long delay
# before the console login prompt appears. devfsadm above has now processed
# this boot's reconfigure, so it is safe to clear for subsequent boots.
# Absolute path per the zyginit boot-script convention.
