| SUBJECT | Re: [Hangout - NYLXS] [artix-general] S6 not starting default
|
I actually think it's just a permissions issue here. s6-scripts starts
up dmesg and pipes it to s6-log for logging reasons. This is stored in
/var/log/dmesg. However, this process is done by the s6log uid/gid. So
if /var/log/dmesg already existed and was owned by something else
(likely root), then this would fail. The startup script has the -e which
means it exits immediately if it receives an error code (i.e. the
/var/log/dmesg failure). The dmesg oneshot is started with the boot
bundle, so that means the default one was never executed because the
script always exited due to the error.
