s6-log can create current with 640?

Is there any way to tell s6-log to set the mode to ./current to
something other than 644? 640 is preferred?

For example: I write to the logdir /var/log/httpd/error which has privs:

/var/log/http
drwx------ 2 uucp uucp 1.0K Oct 23 12:37 error/

Within /var/log/httpd/error
-rwxr--r-- 1 uucp uucp 190K Oct 23 12:37 _at_400000005dafaf1b180d862c.s*
-rw-r----- 1 uucp uucp 0B Oct 23 12:37 state
-rw-r--r-- 1 uucp uucp 0B Oct 23 12:37 current

I did try umask 037 but that just broke the pipe.

All my log files are of this form
#!/usr/local/bin/execlineb -P
s6-setuidgid uucp
redirfd -r 0 /services/ntp/fifo
/usr/local/bin/s6-log -b n28 r7000 s200000 S7000000 !"/usr/bin/xz -7q"
/var/log/ntpd

This is a big deal as I'm about to move my audit processing under s6-rc.

(Aside: Actually I write to a fifo and then redirfd for s6-log to pick
up the content and manage the log files. All works very nicely :) )
