Subject: um: Run UML in it's own session.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=250127216dd6635f5730752d7444bdec992aecb0;p=openwrt%2Fstaging%2Fblogic.git

um: Run UML in it's own session.

If UML is not run by a shell it can happen that UML
will kill unrelated proceses upon a fatal exit because
it issues a kill(0, ...).
To prevent such oddities we create a new session in main().
