the same context (which can be quite a mess). You could either move the
/var/run directory into a namespace specific overlay/filesystem, or you
could use the parameter "global.lockfile" to set your own lockfile (or
disable it completely).

examples:

set a new lock file:
olsrd2_static --set global.lockfile=/var/run/olsrd_1.lock  ...

or disable it
olsrd2_static --set global.lockfile=-  ...


use "olsrd2_static --schema", "olsrd2_static --schema=global" and
"olsrd2_static --schema=global.lockfile" to learn about the parameters of
olsrd2.
