Description: Environment variables (except TERM and LANG) are ignored
if a program is started via service.
If it is started with systemctl, it takes this COMMAND and the values
are correctly passed to the server.
systemctl set-environment SLAPD_MXFAST=0 MALLOC_TRIM_THRESHOLD_=4096
To control them explicitly and to provide the same instructions to
the service and systemctl, it'd be good to have some variables
(SLAPD_MXFAST, MALLOC_TRIM_THRESHOLD_ and MALLOC_MMAP_THRESHOLD_ in
this patch) configurable.
