</div>Hi,<br>
<br>
you're right that systemd itself would function OK without its own<br>
libraries. But it's hard to say what other softwre links to them, and<br>
it'd be irresponsible to move stuff from /lib to /usr/lib without auditing<br>
the users. But we don't want to waste time on this, since the whole<br>
/usr-vs-/ split is obsolete.<br>
