Subject: spawn: downgrade loopback detach errors to debug
X-Git-Tag: v219~498
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=5e4074aa3188ff439c0509908284469807d2749e;p=elogind.git

spawn: downgrade loopback detach errors to debug

Sometimes udev or some other background daemon might keep the loopback
devices busy while we already want to detach them. Downgrade the warning
about it.

Given that we use autodetach downgrading these messages should be with
little risk.
