One thing that I forgot to mention here is that depending on the age of
the libc this might not work properly as written. Newer libc's use
datagram connections for syslog and because of that you need to
hand-write the entire s6-ipcserver chain (since the s6-ipcserver
entrypoint doesn't currently support passing the SOCK_DGRAM option to

If you need to write it by hand, you should change that line to:
s6-ipcserver-socetbinder -m -b0 /dev/log
s6-applyuidgid -U -z
s6-ipcserverd -1

then the rest of the program (the fdmove and ucspilogd commands).
