Cerberus Alpha: Tuning the OS for the Program

By now (version 0.B perhaps?) I had a mostly functioning program and it was time to set to work implementing it into the boot sequence. I implemented a function to try to mount all hard drives (still needs work, more on that later) and turned the main menu into a function of its own. Everything was not working correctly yet and one of the first problems was that the Bourne Shell (#!/bin/sh) was not correctly interpreting the script. Since this script was written to be interpreted by Bash I changed the 1st line to #!/bin/bash. I then had to install the bash interpreter itself and from then on it worked. Fortunately, Tiny core has a very simple and easy way to install programs from the desktop. As a result of installing bash, ncurses was also installed as a dependency which I like because I'm a fairly big fan of ncurses based programs (wavemon and nano to name a couple). Speaking of nano, that was the next thing that I installed. Personally, I can't really stand vi. In my opinion, nano is much easier to use and I like emacs too. I know some people really love vi and vim, so don't let me stop you. I wouldn't really need a text editor in the final version, but since I was still working on it I decided to leave it in. It doesn't add a lot of time to the boot process or the .iso size, so I think I will leave it in permanently in case anyone using the CD could use a text editor. A good text editor. Oddly, there was a single command in my script that was giving the interpreter trouble still, tput. I was using tput to print out a warning in reverse-red text, but it was giving me an error. It turns out that for tput to function it requires ncurses-utils to be installed. Well, ncurses-utils is not very large and it looks like practically the only thing it does is for tput, so I installed it. I ended up taking out this warning later so I may actually get rid of ncurses-utils altogether, but for now it stays in. At this point I'd like to mention that I had to install ezremaster in order to remaster the OS. Technically I didn't need it to do the remaster, but it was a great deal of help. Actually, whoever created ezremaster should really be commended. Once I understood how to use it correctly, it actually made remastering an EZ and painless task. I did not leave it installed in the final .iso, because there is no need for it. Around this time I started working on actually getting the program to run at the correct time, which I eventually did, but much later on I ran into another problem which called for a new program to be installed. When I had everything working perfectly, or so I thought, I burned the .iso to a CD and gave it a shot in a PC at home. It came back with errors telling me the file system was read only. After much investigating, I discovered that TinyCore does not support writing to NTFS file systems out of the box. I guess I must be spoiled by working with such "bloated" Linux distros as Slitaz and Lucid Puppy. Anyway, I found that the program I needed was ntfs-3g. With this installed, it was working well again. One cause of the problem was that I mistakenly formatted my 3 hard drives (in VMWare) as FAT32 instead of NTFS.
