The first steps in creating a remaster is outlined
in this thread at MyPCLinuxOS. Texstar's instructions are concise and will take you through creating your remaster, if you are willing to take the time to do the /etc/skel edits and then go to the next level and look for other files that may need to be edited. More may be learned by perusing the
LXDE Remaster threads and the threads in the
Quarterly Update CD section.
There is more to creating a remaster than simply adding / removing a few apps. It takes time and commitment to search out and edit the files where changes are needed. For example, if you've created or just added a new default log in theme, you need to edit the /etc/rc.sysinit file to be sure you remove the graphic with the liveCD login info on it, as well as adding the graphics to /usr/share/apps/kdm or /usr/share/gdm. You'll also want to check in /root and /home/guest for anything that you may need to edit. Remember to enable "show hidden files" under edit in your file manager. Do not get in a hurry! Accuracy is more important than speed.
If you need to know more about the filesystem,
LinuxCommand has an good
guided tour for the basics. For more in depth information, a web-search is a good idea, I use
Google's Linux search. In this effort to learn you should bear in mind that you may find information that doesn't fit with the PCLinuxOS layout of the filesystem. For this reason, you should review where things are in our system. For example, some distros use /usr/local as the place for app installation, while the default in PCLinuxOS is /usr.
Do complete updates before you start, and as you go along. Working with a completely up-to-date system will benefit your remaster. After you've started, if a new update comes along that may make changes to something that you've already edited, you will need to return to that file or files and review it again. A new edit may be needed.
