Subject: rm-rf: downgrade root check log when directory doesn't exist
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b9ef5951f8f9e156479494fdb9ca6274cb3d3c53;p=thirdparty%2Fsystemd.git

rm-rf: downgrade root check log when directory doesn't exist

When a unit is stopped we try to destroy the credential mount point,
which might not exist. This logs at error level, which is noisy and
pointless. Downgrade to debug level on ENOENT.

systemd[1]: Failed to determine whether '/run/credentials/run-p119516-i119816.service' is the root file system: No such file or directory
