22:00	<uibsysadmin> Hi
22:01	I have a question about LTSP and I think this is the place to ask it, right?
22:03	I would like to create an image (chrooted) in which the users and passwords created in it are kept.
22:04	That is, the passwd, shadow, etc. files will not be modified.
22:05	Is it possible to get what I am asking for? Thank you!
22:09	<vagrantc> uibsysadmin: my first question would be why do you want to do that?
22:11	embedding the users and passwords in the image has security implications ... anyone on your network will have access to that information
22:17	uibsysadmin has left IRC (uibsysadmin!~uibsysadm@206.204.136.92, Quit: Ping timeout (120 seconds))
22:18	uibsysadmin has joined IRC (uibsysadmin!~uibsysadm@206.204.136.92)
22:19	<uibsysadmin> Hi, vagrantc. Thanks for your quick response
22:22	<vagrantc> there may be some other way of accomplishing your goals...
22:22	<uibsysadmin> Our clients must autologin and display only one web page in full screen. There are no more applications, no more documents to save, and once the pc is turned off, everything is deleted.
22:22	<vagrantc> so basically a kiosk sort of setup
22:23	<uibsysadmin> Exactly!
22:23	How?
22:23	<vagrantc> you shouldn't need any passwords at all, then ... just write some hooks to add your user at boot
22:23	and configure it for autologin...
22:24	https://ltsp.org/man/ltsp.conf/ search for autologin ... for the autologin part
22:25	uibsysadmin has left IRC (uibsysadmin!~uibsysadm@206.204.136.92, Quit: Client closed)
22:26	<vagrantc> probably add an FSTAB_x entry to mount the homedir as tmpfs ... a POST_INIT_x to add the user ...
22:27	uibsysadmin has joined IRC (uibsysadmin!~uibsysadm@206.204.136.92)
22:30	<uibsysadmin> AUTOLOGIN="user01"
22:30	That easy?
22:31	Without creating users neither in the server nor in the image? :O
22:36	<vagrantc> see the part about FSTAB... and POST_INIT...
22:38	or maybe you don't need the FSTAB bit ... just something like POST_INIT_USER01=adduser --disabled-password --gecos ,,, user01
22:38	that might populate /home/user01 sufficiently that it will not try to mount /home via sshfs
22:38	otherwise, you might have to mount /home as tmpfs or something
22:41	<uibsysadmin> What if the user and his home are already created in the image? Is that enough?
22:42	<vagrantc> that could work, but then you have to workaround the fact that ltsp deletes all that :)
22:42	which may be possible ... but why do you need that?
22:43	easier to paddle with the river than against it
22:44	<uibsysadmin> What solution would you use?
22:45	<vagrantc> set AUTOLOGIN and POST_INIT_USER01 in ltsp.conf ... and maybe an FSTAB_XX entry as well, if needed
22:46	<uibsysadmin> I only need a browser that displays a web page, and little else.
22:46	<vagrantc> yes?
22:46	<uibsysadmin> Yeep
22:47	<vagrantc> you'll need to crate a custom .desktop file for that user as well, probably ...
22:47	to be able to specify your webbrowser-only environment ... but that is a more complicated subject
22:47	first just get autologin and user creation from ltsp.conf working, then move on to more complicated things
22:48	<uibsysadmin> Don't worry about that! Is resolved yet! :D
22:48	My clients are VDI thinclients.
22:49	<vagrantc> like i say, get the basics working first ... move onto more complicated stuff once you have that
22:50	<uibsysadmin> Thanks a lot, vagrant. I will put your advice into practice tomorrow. Now it's time to sleep. It's too late!
22:50	;)
22:51	<vagrantc> there are other people around earlier in the day too :)
22:51	usually
