For some reason Calibre won't let me do anything because "drive is full" which I assume has to do with this.
Update: I believe I "fixed" the error with Calibre by using FlatSeal to add environment variable CALIBRE_TEMP_DIR that changes the Temp directory to something else. So far that's the only program I've seen give trouble.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
