Changing the default directory structure

If I start a new distro (e.g. LFS):

  1. How can I change the directory structure?
  2. What should I expect after it's ready? (probably can't install most of the packages without modification, right?

But, before you down vote: I've been asked to make a new distro for a specific project which they need (actually, want) a new directory structure with a few changes, for example remove the var and bin directories, but without halting the system. The application of this distro is so limited, so i think it shouldn't be a big deal as they need just a few packages to be installed.

you can create a folder called system and the move all the files into the /system folder. and after that create symlinks, so the system can still be used. example:

su -i

cd /

mkdir system

mv /usr /system/usr

ln -s /system/usr /usr

I just did it........it broke my system XD (i think it was because i moved all the files into /system , including /boot witch is used by GRUB)

The chance of breaking the system is huge if you don't have background knowledge. Example if you move /bin to /system/bin, then you won't be able to create the symlink afterwards because the ln command (which is a program) is located in the /bin folder so moving it will end up in an error.

also, check out gobolinux.org which is based around what i just did. The entire system has been reorganized and to maintain compatibility, they have created symlinks so that they don't have to reprogram an app when porting applications.

These are few pointers that come to my mind and definitely it is not complete:

  1. Your PATH should be updated in the startup scripts like ~/.bashrc, /etc/profile.d, and so on to reflect the updated directories.
  2. Configuration files tend to use /var quite often. (/var/log, /var/tmp) You'd need to modify all these location references.
  3. Basically your kernel is going to start /sbin/init which is going to start the initialization at /etc/rc.d or equivalent. If you start tracing all the scripts and services invoked in these startup scripts, I believe you should be able to capture all the places you'd need to modify the path names.
