Arch Linux

Actually, the line
echo -e "\n# Enable kernel RTC sync\nrtcsync" >> "$pkgdir/etc/chrony.conf"
is in package()

There's another mistake in the PKGBUILD regarding the configuration file:
sed -i 's|.pool.ntp.org|.arch.pool.ntp.org|g' examples/chrony.conf.example*
should probably be something like
sed -i 's|pool.ntp.org|arch.pool.ntp.org|g' examples/chrony.conf.example1
because it replaces the space between the 'pool' directive and argument with '.' .

And also the rtconutc option isn't in in chrony.conf.example1 .

You could change the PKGBUILD less if you used the old conf which is now chrony.conf.example3 .

I just came to report this regression as well -- the PKGBUILD was updated to use chrony.conf.example1 but it should have chosen chrony.conf.example3 to maintain backwards compatibility with existing users during upgrade. The extra examples should then be added to the package under /usr/share/doc/chrony/examples/ to let a user then choose their own other config if the fully commented example3 is "too much" post-install. Also -- example3 is the only one that contains defaults for "offline" mode which works for laptop users (and the network manager dispatcher script).

I've changed example to 3 and install examples into /usr/share/doc/chrony/examples. Please try 2.0-2

The bad sed edits from my 2nd comment are still here.
Like this:
! pool.arch.pool.ntp.org iburst
(with a '.' instead of a ' ').

And there are some namcap errors, dunno if you've seen those.

should be fixed in 2.0-3

Thanks!
Seems fine now
