Add linux kernel modules needed to do kernel tracing with LTTng.
To make them available to lttng in NixOS, add this to configuration.nix:
boot.extraModulePackages = [ pkgs.linuxPackages.lttngModules ];
Babeltrace is a command-line tool and library to read and convert LTTng
tracefiles. Give it a (binary) trace file/dir path and it will print a
human readable event log to standard out.
This is the Linux Trace Toolkit. Included in this package:
Command-line client:
lttng
Tracing daemons:
lttng-sessiond (automatically started by lttng)
lttng-relayd (remote trace collection daemon)
Userspace tracing can be done by using liblttng-ust. To do kernel
tracing we also need the LTTng kernel modules.
I've added a patch that changes "/sbin/modprobe" to just "modprobe".
It has been submitted for inclusion in mainline, so it will probably
make it into 3.11 (or 3.12 as 3.11 is fairly close to release).
It is very local, only affecting people who use the "send" feature.
Without it, send is unstable/unsafe to use incrementally.
It can probably be applied to 3.9 and 3.8 as well, but as I only
tested it against 3.10, so I didn't bother.
It turns out that the .deb only contains the changelog and some other docs.
Revert back to using the i686 version, but keep the double url for the future.
The script installed with this expression only copies a boostrapper and another
script to the user's home folder. Those also need to be patched to get on with
the installation.
The reason behind this is to avoid breaking NixOps while releasing
version 1.0 of nixpart. We could also use nixpart and nixpart1, but the
goal is to have nixpart as a generic part of NixOS instead of being only
used specifically for the Hetzner backend of NixOps.
Which essentially means: The partition syntax will change to be based on
attribute sets and we no longer need to use Kickstart syntax. And that's
the main reason why it will break in version 1.0.
