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.

Safely is always a bit iffy when you're resizing partitions with data on them. Parted and various GUI tools built on top of it can resize partitions without losing data in most cases, but there is always a risk. I wouldn't like doing this without fresh backups.
You can unmount the home partition for resizing when you're not using it, e.g. if you log in as root, which typically has its home directory in /root. This would allow resizing it while running from your installed OS rather than a flash drive.
You don’t need to unmount anything to resize.
