With parallel ports being harder to find on small modern computers I have been re-using older HP Thin Clients to run CNC routers for a while, Most of them have very little drive space (1GB IDE flash cards). AT the moment i have to retrofit a old IDE 2.5" drive in them to run Linuxcnc.
Is there a way the creators could build an image without all the apps pre-installed in debian linux? A lot of them are not needed to just run equipment, Getting the image around 600mb would be awesome, I might take a look at doing it but im not that skilled with Linux lol.
What do you guys think?

I can see the attraction.
I tried deleting a bunch of spare apps from my Debian install, but it turns out that the entire UI has a dependency on Orage Calendar, and if you uninstall that then you end up with a "lighter" installation than you wanted, you have a text-mode terminal only.
You could look at installing an already-available light Linux, then adding LinuxCNC to that.

Yeah,
I looked at a lot of distros based on debian, i did not see any that would stay under that size, Im looking at some different storage options at the moment, Im going to try some PATA to CF card adapters and see if i can get them to work, that would at least make them solid state storage, the old PATA hard drives are getting hard to find and when you do they are used and you never know how long they will last lol.
I also have a 16gb MSATA half card on order to see if i can use that, i hear the Half MSATA cards do not work in the Thin Client im using.

Take a look at the openbox desktop, it's pretty light. As a side note if you make the right selections you can install something other than bloated gnome.

A Debian Jessie minimal install is about 840M.
Pulling LXDE to get a small desktop environment brings us close to 1.7G
We could go a bit lighter with just OpenBox, but ballpark will be between 1 and 1.5 GB -- unless we spend a significant amount of time in looking at what we need and don't.
Also that does not take in account any swap space -- obviously we should not swap, but better be safe than sorry...
Alternatives are the Lightweight distros , but unless we want to rebuild everything ourselves, the ones that are a bit recent and based on Debian (CrunchBang/BusenLabs) are already around the 1G
To avoid to have to permanently fight for space, I would look at solutions with about 4GB of storage space. Anything less than that will be a pain to maintain (4GB IDE flash cards are not that expensive...)

Thanks BigJohnT,
Ill take a look at openbox desktop, Im always playing with new distros that run on my normal computers, currently i run LMDE 2 on all my laptops and media servers.
Thanks Amedee,
I think what you are saying is what im looking into, the Thin Clients im using have a lot of options for adding storage, just not much room lol.

If you have an RTAI kernel then building LinuxCNC (_without_ the docs) isn't too hard or heavy on dependencies.
Building the docs pulls in GB of stuff.

Nice find, I have not seen this type of disk on module before.

16GB shiould be plenty...

Also, depending on your "environment", an alternative could be to use these 'diskless'.
This is typically what I do with the small devices I have at home, as I have a file server running anyway. I do PXE boot if the device supports it, or just have the /boot partition on the device and the rest on the network (e.g. with Raspberry Pi's)
