No Space Left on Device

[Teresa e Junior <teresaejunior@gmail.com>]

Hello!

I have created a well compressed live image of a lightweight system, and
I have a script which decompress a file during the boot. My issue is
that I get a "No Space Left on Device" error. My image won't work on
systems with less than 320MB of RAM. It makes my lightweight system
senseless.

I thought I could solve this by increasing the size of the tmpfs, but
unless I'm doing it the wrong way, seems not to have solved the issue.

Any ideas on how I could increase the temporary device size or
decompress the file without errors. It outputs 140MB of data and then
the compressed file is erased.

Thank you in advance!
