Installed from scratch on CentOS-6.7 x86_64. Comes up out of the box with zero config (another cjdns node was alread on the LAN).
Yum pulled in libuv-0.10.34 as a dependency. The /usr/sbin/cjdroute does not use libuv dynamically, but embeds 0.11.4. I don't know where the dependency came from - I just double checked the SPEC. Ultimately, the goal is to use the system libuv, so I don't think this is a problem.
USB Wifi leaks 4-30kb/s kernel memory, depending on bad packets received. If you have USB Wifi, you might want the patched kernel in koji linked here: https://bugzilla.redhat.com/show_bug.cgi?id=1303270
4.3.3 and 4.3.4 have this regression: https://bugzilla.redhat.com/show_bug.cgi?id=1303270
The system can stay up only 8 hours before crashing with an OOM panic (not due to any user space processes). The BSOD further more leaves the ether nic active in a way that DoSes all devices connected to the same switch.
Stuff seems to work for those 8 hours.
