Installing Linux with minimal size ( < 300 MB)


I have been trying to install Linux with minimal package lesser than 300 MB.
I have tried and put the kickstart which does within 700 MB(first CD) at Installation .
Anyone who have ever tried writing the kickstart file for the same.

No, I did not write a kickstart file, but why not using some small Linux dist. like DSL ?

Zenwalk just released 6.4 'Core' which is what you're looking for (285MB 10min install). Check it out.

I am not sure why centos makes it that big.

As with the others you could put a very much smaller footprint on with some other distro.

I guess you could strip down CD1 to that size.

I'd use astrumi or puppy maybe even tom's boot disk.

Guys,

I knew about the Linux which can even come within a floppy like mulinux and others.
But What I really need is making CentOS very small which should have needed minimal installation like selinux is not necessary and so on.

Have you tried to strip down the CD1?

To get an idea of what packages are needed, for creation of a kickstart file I followed some advice on a centos page
  1. doing a CentOS 5.5 install via the gui
  2. choose custom packages
  3. deselect everything
then
  1. I installed rpmreaper from rpmforge (aka DAG)
  2. then uninstalling anything unwated in yellow
  3. then uninstall anything unwated that has now become yellow
  4. repeat until no more yellow can be uninstalled
  5. go through things with circular dependencies and remove entire circle of unwanted packages

I arrived at the following list (copy it to a spreadsheet for better viewing)

Code:

note that some packages are duplicates with .i386 and .x86_64 and I only chose to remove one of them
also this list has uninstalled all text editors, even vi. Packages marked as D - delete but RemoveWholePackage FALSE have some architecture of that package installed. However even after doing this I still have an installed size of 572MB.

so based on this if you install
  • kernel
  • grub
  • rootfiles
  • vim-minimal
  • yum
  • libgcrypt
and all their dependencies in a kickstart install that does not install anything else it will hopefully be bootable, have vi and yum, but not much else. Which may reduce the installed size further.

I haven't actually done this with a kickstart install yet, you may also need/want
  • passwd
  • hal - for better hardware control and support
  • dhclient - if you allocate ip's with your dhcp
installed in kickstart as they seem important.

I personally also like to have
  • openssh-server
  • screen
for admin on a headless system

however this still leaves a lot of kernel related stuff, that is not needed on all systems.

I think you can also gain a few megabytes with deleting man-pages, /usr/share/doc/* and unneeded locales.
May I ask what you have for a purpose for such a minimal system, and why it has to be CentOS?

I know this is an old thread, but just thought I'd add that I have done that kickstart thing on CentOS 6 and it didn't reduce the size much at all.
Also note rpmreaper is now in the CentOS EPEL repo, and has been for some time. I still find it a handy tool for looking in to dependency related things.
http://fedoraproject.org/wiki/EPEL

The easiest way to install the EPEL repo on a CentOS 6 install is to run this command as root
Code:
rpm -Uvh --force http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
