Ok, getting closer. Here's a suspect part of Shepherd strace log:
--8<---------------cut here---------------start------------->8---
[pid 1] stat("/etc/localtime", {st_mode=S_IFREG|0444, st_size=2298, ...}) = 0
[pid 1] write(9, "shepherd[1]: changing HTTP/HTTPS"..., 86) = 86
[pid 1] getpgid(194) = 194
[pid 1] kill(-194, SIGTERM) = 0
--8<---------------cut here---------------end--------------->8---
I think the problem is introduced by commit
1e7a91d21f1cc5d02697680e19e3878ff8565710 in Shepherd.
"(getpgid <guix-daemon-pid>") returns 0, and calling "(kill 0 SIGTERM)"
kills all processes.
Now, I really don't get how guix-daemon pgid could be zero. Man page of
setpgid(2) says:
--8<---------------cut here---------------start------------->8---
A child created via fork(2) inherits its parent's process group ID. The PGID is
preserved across an execve(2).
--8<---------------cut here---------------end--------------->8---
WDYT?
Thanks,
Mathieu
