I'd like to review this.

Could you update the package for 0.2?

OK, please wait.(This software has released many versions recently :( )

NEW Spec URL: http://cicku.me/dhcpy6d.spec
NEW SRPM URL: http://cicku.me/dhcpy6d-0.2-1.fc20.src.rpm

There are few problems:

1. the log file must not be the part of rpm, use:
%exclude %{_localstatedir}/log/%{name}.log
The log file should be still created in the %post section.

2. normally a daemon needs to be installed under /usr/sbin, so:
%{__python} setup.py install --skip-build --prefix=%{_prefix} --install-scripts=%{_sbindir} --root=%{buildroot}
and in the %files section:
%{_sbindir}/%{name}

3. Group:             System Environment/Daemons

A bit more difficult problem is converting dhcpy6d
to run as non-proviledged user, perform user creation/removal in the %pre/%preun
sections, and write the corresponding systemd service file (the current one
is not working).

I'm working on a dhcpy6d.spec, based on yours,
for other distributions: EL6, openSUSE:

I forgot to remove this, I'll fix it.

We don't need to do this unless you consider this is a MUST.

I don't give every my package a Group tag, Group tag in Fedora is not a MUST.

Yeah, can you tell me why you want it to run as non-root user?(I need an answer)

i'm not sure. It seems this is what fhs still recommends: http://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard

maybe starting as non-root is no longer recommended with systemd, but was a common practice with system V. I see for example that /usr/sbin/sshd runs as root on fedora 20, on the other hand 
http://twistedmatrix.com/documents/13.0.0/core/howto/systemd.html recommends non-root.

Hi,

i prepared patches for the spec and service file:
http://marcindulak.fedorapeople.org/packages/dhcpy6d/v01/dhcpy6d.spec.patch
http://marcindulak.fedorapeople.org/packages/dhcpy6d/v01/dhcpy6d.service.patch
Please review them.
After these changes restart,start,stop of dhcpy6d.service works.
I haven't tested any dhcpy6d functionality though.

Hi,

Thanks for your patch, I will look into it later.

After some discussion I finally decide to let dhcpy6d running under its own user/group.

So I'll update the request later.

Some files are incorrect indeed, I've fixed.

For the log file touch, should we need to touch that file? Currently I just removed the log in %install section.

running as non-priviledged user
may require dhcpy6d working together with the authors of dhcpy6d,
as the server wants to open a low port 547.
So maybe let's leave it running as root for now.

yes, we need it. To test that:
rm -f /var/log/dhcpy6d.log
yum install dhcpy6d*.rpm
systemctl start dhcpy6d
grep "dhcpy6d: IOError" /var/log/messages
In order to verify that dhcpy6d does not run correctly as
non-priviledged user, do as root:
touch /var/log/dhcpy6d.log
systemctl start dhcpy6d  # /var/log/dhcpy6d.log unwritable by dhcpy6d
chown dhcpy6d:dhcpy6d /var/log/dhcpy6d.log
systemctl start dhcpy6d
grep "dhcpy6d: socket.error" /var/log/messages

Let's focus on getting dhcpy6d to work as root.
We have contacted the authors of dhcpy6d about running it as
non-priviledged user.

Updated.

Please check again:

NEW Spec URL: http://cicku.me/dhcpy6d.spec
NEW SRPM URL: http://cicku.me/dhcpy6d-0.2-2.fc20.src.rpm

It works for me with settings from dhcpy6d.service.patch bug#961180#c7
(Type=simple and run as root). Can you test systemclt start/stop on your Fedora machine and confirm that Type=forking hangs? Different types are described in
man systemd.service. I think it may be also a good practice to have
syslog.target in After - dhcpy6d performs logging.

There is one spelling left:
dhcpy6d.noarch: W: spelling-error %description -l en_US dualstack -> dual stack, dual-stack

NotReady: we are waiting for the next release of dhcpy6d which will run as non-priviledged user. It's already on github https://github.com/HenriWahl/dhcpy6d , but not released yet.

Hi, any progress here? There is already a new version of dhcpy6d

Busy now, will update later.

I'll be closing this due to inactivity in one week
