Hello, The documentation for s6-ipcserverd repeats two times IPCREMOTEEUID in the last sentence of the "Environment variables" section. The second ocurrence should be IPCREMOTEEGID.
* http://www.skarnet.org/software/s6/s6-ipcserverd.html The documentation for s6-ipcclient has a dead link to the s6-sudo page in the "Notes" section, because the URL is missing a final '.html'. * http://www.skarnet.org/software/s6/s6-ipcclient.html G.
