What will be the effect of HOME env var not being set?
cant the app log without this env var? or can we ignore this warning?
Thanks,

Perhaps LTTng-UST should do like LTTng-tools: try $LTTNG_HOME, then
$HOME, then the current UID's entry in /etc/passwd? This would avoid
disabling per-user tracing even when the environment variables are cleared.
WDYT?

What's the impact of this?
What will happen if we see this error "disabling per-user tracing".
Will the app stop tracing?
Thanks
