# Script fragment to make dhclient supply nameserver information to resolvconf

# * Be careful about changing the environment since this is sourced
# * This script fragment uses bash features
# * As of isc-dhcp-client 4.2 the "reason" (for running the script) can be one of the following.
# (Listed on man page:) MEDIUM(0) PREINIT(0) BOUND(M) RENEW(M) REBIND(M) REBOOT(M) EXPIRE(D) FAIL(D) RELEASE(D) STOP(D) NBI(-) TIMEOUT(M)

# (Also used in master script:) PREINIT6(0) BOUND6(M) RENEW6(M) REBIND6(M) DEPREF6(0) EXPIRE6(D) RELEASE6(D) STOP6(D)
# (0) = master script does not run make_resolv_conf
# (M) = master script runs make_resolv_conf
# (D) = master script downs interface
