Installing Remastersys was a bit problematic, since I had some issues with authenticating the repository key. Once I got past this, I then ran into errors during the installation as well. As it turned out, it was an issue with a conflict between remastersys-gui and remastersys-gtk.
Apparently, I needed to select remastersys-gtk. Upon first run of the Remastersys front-end, I was presented with the warning to close anything I had open. There was also the suggestion that I unmount any network shares. Sound advice, as this sort of thing could create problems when rolling your own distro.
Since it had been awhile since I’ve used Remastersys, I was surprised at how well the software buttons were laid out.
Backup – This is the button to make a complete backup of your existing Ubuntu installation.
Dist – The option you’d choose to if you wanted to create a distributable version of your installation.
Distcdfs – Same as Dist, except that you are free to add additional files to the CD _ for example, if you wanted to add a different browser. This is where you would do your file customization.
Distiso – After adding additional files using Distcdfs, you would then use this button to create the ISO for your distro CD.
Clear, Boot Menu image for LiveCD, Boot Menu image for installed environment, User settings, and Plymouth theme are also provided after Distiso. On the Settings tab, you will find additional advanced settings such as files to skip, CD naming scheme and Squashfs options.
