Subject: Fix: expand load path to an absolute path before daemonizing
X-Git-Tag: v2.9.11~19
X-Git-Url: http://git.liburcu.org/?p=lttng-tools.git;a=commitdiff_plain;h=aacbfa47ad16d5778726b678c095b824d75d388b

Fix: expand load path to an absolute path before daemonizing

Relative paths must be expanded before the sessiond is daemonized
as the CWD is then changed to '/'.
