[gentoo-user] supervise-daemon fails to start openrc-user

[ralfconn <mentadent47@yahoo.com>]

Hello,

starting from yesterday's update on one of my systems (RaspberryPi) I 
get the following when I ssh into it:

pihole pam_openrc[some_user][4421]: starting session
pihole pam_openrc[some_user][4421]: 1 sessions
pihole supervise-daemon[4645]: Supervisor command line: supervise-daemon 
user.some_user --start /usr/libexec/rc/bin/openrc-user -- some_user
pihole supervise-daemon[4647]: Child command line: 
/usr/libexec/rc/bin/openrc-user some_user
pihole openrc-user.some_user[4647]: uid 0d, gid 0d, euid 0d, egid 0d.
pihole supervise-daemon[4646]: /usr/libexec/rc/bin/openrc-user, pid 
4647, exited with return code 255
pihole supervise-daemon[4656]: Child command line: 
/usr/libexec/rc/bin/openrc-user some_user
pihole openrc-user.some_user[4656]: uid 0d, gid 0d, euid 0d, egid 0d.
(the last three lines repeated over and over, then:)
pihole supervise-daemon[4646]: respawned 
"/usr/libexec/rc/bin/openrc-user" too many times, exiting

I never noticed supervise-daemon 
(https://wiki.gentoo.org/wiki/OpenRC/supervise-daemon) before, I suppose 
it is a new component of OpenRC. From the above log I understand that 
pam is trying to start an openrc session (whatever that is) for user 
some_user but fails. supervise-daemon tries to restart the service 
several times and finally gives up.

Any idea why openrc-user is failing? And what is an openrc user session?

The ssh succeeds but with a longer delay compared to previous version of 
OpenRC, which is now sys-apps/openrc-0.60.

thanks,

raffaele
