ZMLiveCD 2008

boot splash wise, i liked the last zmlive cd splashes... linux cop did it for me.

Alternativly we have Coreys ones from the ctu zm project.

Until we have anything better i suggest we use these.

As it appears we have mmx sorted already then i think all we need is the self healing bit to be looked at. I dont understand enough about mysql to write these so any takers?

*just reread the thread.
Techno i think your doing a good organising job i say keep that up.
Do we have a basic iso yet as im about to start one if we havnt but if its been done i cant see the point of duplicating.

ok then i now know why i use the live cd....

trying to build a basic starter live cd with a few mods as a base point.

All goes great apart from one dependancy on ross's pclos rpm

libavcodec.so.50

any ideas? It looks to me to be part of ffmpeg and im assuming its now in a different place than it was?

This may be obvious but want to mention it anyway. On a system running ZM on Pclos, if you try to keep it updated and start applying the updates that are released for Pclos, you may find that even if ZM keeps working ok and the remaster is succesful, that new iso may not produce a new working ZM installation.
So, just in case, remaster or make a copy of your installation before applying updates. Remaster after updates and install this new iso to make sure it works.

I do not know which are the packages that harmfull but it has happened to me.

I really like the approach. This is true in non-linux environments too.
On this particular project, it would be great to have a step-by-step guide, for doing this.

I have hit a brick wall ross
Im assuming that ffmpeg has been updated AGAIN and this hos broke the rpm.

stuck now. I should have built a cd as the wiki says but i think the info is too old now.

I can host it once its made as long as bw aint silly

I has learned the hard way on remastering and am sure there are new problems to come but i think remastering is a great idea no matter what problems you could find.

About the Guide, i do not have a ordered way of thinking to make a guide but can tell you what i do.

I partition the disk manually hda1=/ (16gb, ext3) ,hda5=swap (2gb) and hda6=events(rest, reiserfs).
I has not find (but has not spend time looking howto) the way to remaster excluding the subdirectories that keep the events. What i mean is that i do want subdirectories 1,2,3,4.etc but do not want to include in the remater what is under them. So, i delete all events first. The follow the standard procedure. Most of the time the iso is larger that a cd.
I use vmware or a extra harddisk to install this iso and play with it for a while using a webcam.

I put up a skeleton some time ago for this purpose -
http://www.zoneminder.com/wiki/index.ph ... Production

It needs to be edited by each of you who are actually following a process, that way we can have a uniformed approach to the build. I've been wanting to build one myself, but I don't want to reinvent what the other guys are doing.

I'll be happy to keep the wiki clean, just add your steps and I'll verify and organize the notes. What we will end up with is a nice set of instructions to make the livecd for NEXT year with much less effort ...

Mind you, my skeleton is just there to start from - don't be afraid to make major changes as I have no clue if my steps are accurate.

Go for it!

Similarly, I'd like to know how to 'retain' the modprobe.conf file after remaster - during install the file is overwritten. I'd like to have my live cd's for each piece of hardware (capture card) I use.

I think it's something like making a file called 'modprobe.kmc4400' or whatever, but I haven't experimented with it. Confirmation?

Remastering is a way to clone your actual installation on different equipments with different hardware. That is why some files like your modprobe.conf is replaced by a clean one. Once you install from this livecd (remaster on), as far a i know, the hardware is scanned again even if is the same machine from which you made the licecd.

As you say, maybe copying it with different name is the solution.

When i need to do a full backup i usually connect a second hardisk o a usb hardisk and use
cp -avr /dev/hda1/* /dev/hdb/
This way the files are not changed.

It would be interesting to remaster and the install in a second hardisk and compare each file of both disk to see what else may change.

i think we need to have a post install script that is run on first login after install.
Stuff like custom modprobes could be done then

I installed zm 132.2 pclos alfa and try to update it. Libavformats50 is marked to be removed as ZM too. I unmark libavformats50 and ZM was unmarked automatically. Then update everything else.
It seems to be running ok from harddisk. Then i remaster it and burned a CD. I booted from this liveCD but i could not see the picture on the screen from the only camera i had connected. No blue screen, just white where the picture should be. It seems to be recording (did not have time to check it) and /dev/video0 was not red on the main screen.
Then i booted back from the Harddisk (the one used for remaster) and again try to update what was left from first update. ZM was erased. Tryed to install the Livecd i justr made and while installing, once the part for parttioning hard disc is passed,(i choose "use existing partitions") nothing else happend. The installation breaks.
Any idea which package may be broken?
I came with a not usable remasteredlivecd. Could not run ZM and could not install.

Here is a low key announcement, buried deep in this long running thread

I uploaded a new livecd solution Ive been working on, and some docs describing it. It's a departure from past zmlivecd solutions.Check it out when you get some time.

Wow! Looks nice!

OFF:
Regarding Asterisk, does it have FoIP (Fax over IP) capabilities? Or is there any linux-based solution for FoIP? That's another thing I'm interested in, maybe one of you has an idea...
