Please add a check for available disk space....

Greetings,

A friend of mine was trying to install and set-up LinuxCNC. He's new to the ways of *NIX. Installation failed because of insufficient disk space, yet said NOTHING about it until it failed.  He's using a small industrial PC with a 128GB HDD.  A simple test for available free space would have prevented what happened to him.  As a UNIX/Linux developer of 30 years+, I've incorporated a lot of these sorts of things into the software I've written.

GIGO! (garbage in, garbage out)  Keep the GARBAGE out of the input stream!

Regards

Unfortunately the linuxcnc iso depends on the Debian installer, any things like checking for enough free space would be something the Debian devs would have to implement. Probably not want you want to hear but that is the situation.
To be fair a complete install can be accomplished with a 16GB disk.
Did your friend have another OS on the disk ?
What was the situation that led to the install failing ?
Surely with your experience you should know to provide more information.
You should have known to ask for more information from your friend.
