ipaclient-install.log

Description of problem:

i don't know why (we have problems with either dns or ipv6 on our network recently??) but ipa-client-install was hanged on:

  ntpd -qgc $tmpfile

ntpdconf.py:

    tmp_ntp_conf = ipautil.write_tmp_file('server %s' % server_fqdn)
    try:
        ipautil.run([ntpd, '-qgc', tmp_ntp_conf.name])
        return True
    except ipautil.CalledProcessError:
        return False

it would be nice if you would enable (if applicable) debug even for all spawned commands, thus 'ntpd -d -qgc $tmpfile'.

the hanging command has following output while executed in different shell:

# /usr/sbin/ntpd -qgc /tmp/tmpVYBemI -d
