Updated from your copr repo. The problem persists.

trace-cmd version 3.1.1 (not-a-git-repo)

usage:
trace-cmd [COMMAND] ...

commands:
record - record a trace into a trace.dat file
set - set a ftrace configuration parameter

...

dump - read out the meta data from a trace file
convert - convert trace file to different version

[root@manet ~]# ls -l /usr/lib64/libtrace*
