Nah, this is not entirely true.

We mount the virtual API file systems such as as /proc or /sys with
mount() system calls, but normal file systems via /bin/mount, since that
is part of the FS mounting API. (i.e. think smbfs and others with mount
"plugins" via /sbin/mount.smbfs and so on).

In fact, the default of StandardOutput= should already by syslog for all
mount units, and it should work. If it doesn't work, it's a bug that
should be fixed.
