[Gluster-devel] Integrating liburcu source into the glusterfs source tree

[Kaleb KEITHLEY]

Hi,

Just FYI, what you propose is called bundling in Fedora packaging 
parlance, and Fedora's packaging guidelines forbid bundling. It is 
possible to get an exception granted, but it's not safe to presume that 
an exception will be granted.

(For downstream this is a non-issue, but here on gluster-devel we're not 
concerned with downstream.)

You either need to convince the maintainers of liburcu to update to the 
newer versions everywhere, or you need to implement using the oldest 
version on the platforms you intend to support. And if this is too 
onerous, e.g. to use what's in (RH)EL5, then it's another argument in 
favor of dropping support for (RH)EL5. (The other argument is that 
python on RHEL5 is too old for geo-rep.)

In short, those of use who package gluster in Fedora would be, however 
reluctantly, required to vote against doing this. I recommend contacting 
the liburcu maintainers in Fedora/EPEL and see if you can't convince 
them to update to the newest version.

Regards,
