stretch-i386.img booted and logged in with the first try :)
03:04
The "username" field in LDM is too small, it cuts off part of the greek translation there...
03:05
"Όνομα χρήσ|τη:" ==> it's cut where I put the |
03:06
.....and it does have the shutdown issue :D
03:07
It's nice that systemd shows the messages in any vt
03:12
Stretch boots with 64MB clients as well...
03:32
vagrantc: for me, the cause of the 1.5 minute stalling at shutdown is caused by /etc/network/if-up.d/epoptes-client
03:33
This is because it's trying to relaunch itself (the automatic reconnection issue, it doesn't auto-detect shutdown on stretch for some reason)
03:33
When you were seeing that shutdown delay, did you also have epoptes-client installed?
03:34
I'll try to get this fixed in epoptes

<alkisg>
vagrantc: this should fix the 90 sec shutdown delay issue: http://bazaar.launchpad.net/~epoptes/epoptes/trunk/revision/508
15:38
<vagrantc>
alkisg: i think you'll actually want to check for /run/systemd instead of the presence of /bin/systemctl
15:38
alkisg: or rather, both.
15:39
i think that's the "proper" way to determine systemd is running.
15:40
systemctl may be installed even if another init system is running.
15:40
[ -d /run/systemd/system ] && [ -x /bin/systemctl ]
15:43
<alkisg>
vagrantc: if systemd is installed but not running, that systemctl list-jobs command will return false, so it's ok I believe
15:43
There's an issue left, that we don't quit on shutdown of non-systemd installations, but that was OK so far, it's not a change in behavior...
15:44
<vagrantc>
alkisg: it's just better to do a directory check, so as not to require calling the binary
15:45
directory checks are cheaper that calling binaries
15:45
<alkisg>
It's just once per shutdown or disconnect, it's not that much of a performance hit...
15:45
<vagrantc>
but it's so easy.
15:45
<alkisg>
Hehe
15:46
<vagrantc>
i mean, if it were incredible convoluted, that'd be one thing
15:46* alkisg did google for a minute on how to detect if systemd was running or not, but didn't see that nice /run check in the first hits...
15:47
<vagrantc>
yeah, i've been looking for the official documentation on that ... when i had to fix ltspfs to support systemd, one of the debian systemd maintainers pointed me to it
15:47
but i don't recall where it was
15:47
<alkisg>
Was /run always a volatile system? Aren't there cases where it's not completely cleared on boot?
15:50
<vagrantc>
always.
15:50
the whole point of /run is that it's volatile and is reset at reboot
15:50
if it's not, it's broken

vagrantc: I pushed --overwrite the [ -d /run..
16:27
...change, whenever you get the chance to test, see if it solves your shutdown issue
16:30
Btw, our screen scripts run too early under systemd, e.g. I first see SCREEN_02=shell, and *then* the target "sound card" is initialized

16:41
otherwise tty0-tty6 fight for control

17:53
<alkisg>
We could just replace the tty* scripts or the inittab entries or the upstart scripts with our own
17:55
<vagrantc>
i tried figuring out how, but it looked a bit complicated
17:55
<alkisg>
When everyone settles on systemd, we'll do it properly with systemd units, no worries
17:55
<vagrantc>
i mean, i know how in sysv init, and upstart ... but systemd did some dynamic thing with the ttys ... which is actually kind of smart... but troublesome
17:56
if we implemented proper systemd unit files for it, it might e easier
17:56
<alkisg>
I did find documentation on how to overwrite the dynamic ttys of systemd (although it was months ago, I don't have it handy)
17:57
And I think it was possible for us to do it dynamically as well
17:57
I.e. only start screen script 02 when the user switched to vt2
18:00
Although, if we start using lightdm, screen scripts might not be feasible... I don't know if we can start it in wherever vt we want, or in multiple vts
18:04
<vagrantc>
yeah, some things will have to change
