Hi back,
The FASTBOOT_URL option in thinstation.conf.buildtime finally works. I just forgot a little piece of conf :
In your pxelinux.cfg/default file, you have to add the LM=# which Don talked about in his previous mail.
I put LM=3 in mine (I use my own pxe files), because, that's the value I found in default file built by thinstation (build/boot-images/pxe/boot/pxelinux/pxelinux.cfg/default)
This LM option has to be present, I forgot it in my previous summary.
Do you want me to make a clean doc about fastboot somewhere ? I didn't find all this on the net, and I know you don't have time enough to make all the doc. If I could help this way, tell me. It won't be a complete doc, of course, but at least the basics to have it working in most cases, that can be completed.

After many more tests, I finally managed to get fastboot working.
As Elio Coutinho wrote in his last mail, I had to add the fastboot_url options to the append line in my pxelinux.cfg/default file.
BUT it didn't work with the web server's name : I had to use its IP Address. It seems that name resolution isn't ready at the time lib.squash should be downloaded.
However, it doesn't work if I activate this option in thistation.conf.buildtime, even with IP Address in place of server's name. I tried many syntaxes for the server's address (with or without quotes, with or without http:// at the beginning...). I can't understand why.
I have two more questions :
In build.conf file (comments to param fastboot), you talk about "squash lag". Does this option affect performances of clients ?
I noticed http (wget) loading of files is much more faster on my network than tftp (that's why I tried fastboot option). Maybe I should only have used the net_file_method=wget ? Does it work for initrd loading, or only for conf files, later ?
To summarize what I finally did (it could eventually be usefull for others) :
- Activate in build.conf :
param fastboot true
package autonet
(package networkmanager was already commented, and stays like this)
param initrdcmd "gzip -9"
(this option contained "squashfs" first, I found this on a forum (Don's advice that solved someone's issue with fastboot). I'm not sure it's usefull, but I didn't try back with "squashfs" since it works for me)
- In pxelinux.cfg/default :
add "FASTBOOT_URL=http://ip.of.web.server/" (without quotes) at the end of the APPEND... line
(put the lib.squash file in this place on the web server, of course.
Thanks for your help

Fastboot needs to know where to look to find the lib.squash. We tell where by putting LM=# at the end of the kernel cmd line. I think 4 is for PXE, but the cmd is updated with every build. You just need to copy the pxelinux.cfg with every build in addition to vmlinuz, initrd and lib.squash

This is not my case. I made the tests with the same PC I use for all my
thinstation tests, for a long time.
I only changed fast boot options in conf files.
I looked at net conf on the client after boot (I launched busybox on
tty2 and used ifconfig) : everything was OK)
Just for the record : I also tested with autonet rather than netwokmanager
