vagrantc, re: fake_hwclock, ltsp clients cant use that as they dont have a local file to store the time
03:52
thats precisely a good reason to do something in a ltsp specific way
03:53
we have a server but not a local file system....
03:53
<vagrantc>
alkisg_android: but fake-hwclock will at least set the clock to the installation time
03:53
<alkisg_android>
not good enough fsck will fail
03:53
<vagrantc>
where is fsck used?
03:54
<alkisg_android>
and certificates will be invalid
03:54
if the client happens to have a local hd or sd card
03:55
ntpdate takes too long to sync because it needs to wait until net up
03:55
<vagrantc>
alkisg_android: timesyncd should happen soon enough for all of that
03:56
<alkisg_android>
so it happens after ldm loads
03:56
i dont know if systemd does it better
03:56
any reason not to trust the server and do it with 1 line at init-ltsp.d?
03:57
<vagrantc>
so my only concern is fighting with ntpd/timesyncd or something by messing with the time
03:57
ok, init-ltsp.d could make sense, or even in the initramfs
03:57
<alkisg_android>
time deamons are loaded after init ltsp.d
03:57
<vagrantc>
right
03:57
<alkisg_android>
cool
03:58
<vagrantc>
so our hook can get it in the ballpark and then the sync daemons should do the rest
03:58
<alkisg_android>
right
03:58* vagrantc saw nbd got support for copy-on-write dirs
04:02
<alkisg_android>
link?
04:03
btw overlay's workdir also affects our cleanup.d
04:03
no maybe ltsp-pnp doesnt work in jessie?
04:04
so
04:08
and for some reason ubuntu still calls it overlayfs so our scripts should check that too

vagrantc: a user asked to have the date at the ldm login screen, I'll commit it upstream if you don't mind...
04:44
Maybe an LDM_DATE_FORMAT lts.conf variable which defaults to just time?
04:46
http://manpages.ubuntu.com/strftime
04:48
Ah we have LDM_12HOURCLOCK now, the DATE_FORMAT will be able to deprecate this...
04:59
Maybe LDM_CLOCK_FORMAT or LDM_TIME_FORMAT instead of LDM_DATE_FORMAT
04:59
OK implementing it...

ltsp-pnp should work in jessie, but once the 4.0 kernel hits stretch it won't work there
05:53
the only code i modified to support "overlay" also still supports "overlayfs"
05:54
alkisg: regarding NBD cowdir support: https://tracker.debian.org/news/685147
05:57
whatever date information should be in UTC ... maybe even just date +%s
05:58
and then the formatting should just be adjusted appropriately
05:58* vagrantc hopes alkisg reads the logs...
05:58* vagrantc always thought the 12HOURCLOCK format was stupid
05:59* vagrantc waves

07:36
<work_alkisg>
vagrantc, about overlayfs, the problem is that in your code, you're assuming "overlayfs" needs the "old style parameters, without workdir",
07:36
and "overlayfs" needs the "new style parameters, with workdir"
07:36work_alkisg is now known as alkisg
07:37
<alkisg>
In Ubuntu that's no longer true, as "overlayfs" now needs the "new style parameters, with workdir"
07:37
So your code only supports overlayfs for older Ubuntu versions
07:38
In another project (lxc) they say "just try to load with workdir first, and if it fails, try without workdir): https://lists.linuxcontainers.org/pipermail/lxc-devel/2014-October/010686.html
07:39
Committed LDM_CLOCK_FORMAT in http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ldm-trunk/revision/1576
07:40* alkisg thinks http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ldm-trunk/revision/1569 and the previous commits made LDM delay for an additional 10 seconds when the user enters a wrong password...

Hi. Back in my last week issue about SCREEN_02=shell not working for Debian jessie.
14:31
by investigating there's a diff beween ltsp-client-core and ltsp-client.
14:32
it works with ltsp-client meta package but not ltsp-client-core
14:32
TRying to find which package missing.
14:47staffencasa_ has left IRC (staffencasa_!~staffenca@8-220.ptpg.oregonstate.edu, Read error: Connection reset by peer)
14:50
<alkisg>
vagrantc tested it and he reported it worked fine
14:50
raphr: You're supposed to have ltsp-client installed, not just ltsp-client-core
14:51staffencasa has joined IRC (staffencasa!~staffenca@8-220.ptpg.oregonstate.edu)
14:52
<raphr>
alkisg: thanks reporting to vagrantc. As I was unsure about bug didn't file it.
14:56
anyway. Just adding ldm package with ltsp-client-core is working.

14:57
<raphr>
In Wheezy , to have ltsp shell only ltsp-client-core was necessary
14:58
needed
15:00
<alkisg>
You would mention that in the bug report :)
15:00
Or, try to come to IRC about 8 hours later, vagrantc might be here then

alkisg: OK thanks. I check with a new ltsp-buid-client
15:16vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc)
15:21
<raphr>
I've found the missing package.
15:22
ltsp-client-core + dbus = working SCREEN_02=shell config
15:25
<alkisg>
so ltsp-client-core needs a dependency on dbus to have SCREEN_02=shell in jessie?
15:25
That sounds strange, maybe vagrantc knows more
15:28
<vagrantc>
hm.
15:30
<raphr>
yes. Quite strange. I think it adds sort of systemd backward compatibility
15:33
without dbus it works but getty takes over the console just after.
15:34
<vagrantc>
i can confirm
15:34
raphr: could you please file a bug report in debian about this?
15:35
<raphr>
vagrantc: OK
15:36
<vagrantc>
when i removed dbus, it also removed: dbus* libpam-systemd* policykit-1*
15:37
but simply installing dbus "fixed" the issue
15:38
<raphr>
which severity ?
15:38
<vagrantc>
important
15:39
<raphr>
OK

when i run ltsp-build-client command, it downloads all files from network..there is network issue in my area...is it possible to install it using ubuntu iso installation file

as long as the ISO contains all the necessary packages, yes.

ravi: ltsp-build-client --mirror file:///media/cdrom --accept-unsigned-packages ... i think that should work

okk..

maybe also --security-mirror none and --updates-mirror none

with the CD mounted on /media/cdrom
