-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello All,
I have used Linux as my primary desktop system 1999 until July 2019. I have used Lubuntu Live for 5 other systems, as well as a few Raspberry Pis running Linux. I have configured and compiled more Linux kernels than can be imagined as well as many major and complex OSS source packages over the years. Currently this eMail is in reference to Lubuntu 19.10 Live image. I have a unique need in a Lubuntu Live image. Currently I use a method of unravelling the ISO and then chroot into the unravelled image to customize. This time customization requirements have expanded. This expanded customization adds in a number of unique scripts that have no impact to how a Live image is created or functions. The expanded customized scripts do need to know some basic system information and when this information is enabled. The information in question is when the lubuntu user is created and when the host name lubuntu is set. I have searched all over the internet for information related to the casper based Live image configuration. The research has indicated multiple times that the Username and Hostname are set in the casper.conf file. That seems simple enough, but I seem to find a gap in this information based on the Lubuntu Live image. This is why I am sending this message to the mailing list in hopes what I have found thus far can have the gaps I have been unable to determine by research and digging into the Lubuntu Live image files. On the Live image I have found two /etc/casper.conf files. One in the initrd and one in the filesystem.squashfs. Both of these casper.conf files show a ubuntu for the Username and hostname. By contrast when I look at the /tec/casper.conf of a booted live Lubuntu the Username and Hostname in the /etc/casper.conf show lubuntu for the Username and Hostname. The question then is when how did the /etc/casper.conf on the Live unionfs/aufs file system change to reflect the expected lubuntu values for Username and Hostname? Am I missing something very basic in my search of the files on initrd or filesystem.squashfs that would answer this question or is there some intermediate script effecting these changes? John L.
