I think were getting closer:
I did:
- I edited /etc/default/asterisk to include :
AST_USER="root"
AST_GROUP="root"
# systemctl daemon-reload
# systemctl start asterisk
# ps aux | grep asterisk
root 3602 7.1 2.5 60332 26012 ? Ssl 16:00 0:03
/usr/sbin/asterisk -U root -G root -g
# rasterisk
# pkill -SEGV asterisk
Then console showed:
Segmentation error (core dumped)
and a /core file is created
I also tried with asterisk run asterisk user and group and looked for any
newly created (find / -cmin -2) : nothing looking like a core file, though
I might overlooked it.
So, it really look like a configuration issue: "how to specify, with
asterisk and systemd among others, where core files are dumped ?".
I'll read again this thread advices and report back here.
