Description Christopher Head 2022-03-17 04:51:18 UTC
DHCPCD ships with /lib/dhcpcd/dhcpcd-hooks/50-ntp.conf, whose purpose is to take NTP servers from the DHCP reply and communicate that information to the system local NTP client. When deciding which config file to update and what kind of NTP client is running, it looks for the following list of config files:

: ${ntp_confs:=ntp.conf ntpd.conf chrony.conf}

in the following list of directories:

: ${ntp_conf_dirs=/etc /usr/pkg/etc /usr/local/etc}

Unfortunately, Chrony in Gentoo installs its config file at /etc/chrony/chrony.conf, not /etc/chrony.conf, so DHCPCD does not find it and falls back to the default of assuming you are running NTPD instead.

To add further annoyance, I could simply have added “-e NTP_CONF=/etc/chrony/chrony.conf” to the dhcpcd invocation, except that /etc/init.d/dhcpcd doesn’t have a variable for adding extra user-specified command-line parameters in /etc/conf.d (and setting command_args in the conf.d file, at least in my experiments, did not appear to work).

Reproducible: Always

Comment 1 William Hubbs gentoo-dev 2022-03-18 06:00:05 UTC
@Sam:
Do you know why we install chrony.conf in /etc/chrony instead of /etc?
I looked at the chrony ebuild and didn't see a reason for this.

Thanks,

William

This dates back to when the package was added in 2002.

I'm fine with moving it as long as we install a compat symlink. Could you give a patch?
