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.

It depends, if your docker installation uses /var, it will surelly help to keep it separated.
For my home systems, I have: UEFI, /boot, /, home, swap.
For my work systems, we additionally have separate /opt, /var, /tmp and /usr.
/usr will only grow when you add more software to your system. /var and /tmp are where applications and services store temporary files, log files and caches, so they can vary wildly depending on what is running. /opt is for third-party stuff, so it depends if you use it or not.
Managing all that seems like a lot of effort, and given my disk issues havent yet been fatal, ill probably not worry about going that far. Thanks for the info though.
No effort at al. You define them once at install time and that's it.
For added flexibility you can use LVM volumes instead of partitions, they make resizing operations a thing of joy.
BTRFS also has something like subvols baked in, but I haven't looked into it.
Getting the size wrong and needing to resize is the effort part for me. Resizing/moving my partitions is always a pain.
Once you learn about LVM, you'll never use a naked partition again. Or your money back.
Thanks for your consultation about lvm.
I'll take a look.
Last time i used LVM was way back in fedora 8 days, when it was the default partition. It was super annoying to use, as gparted didnt support it, and live cds often had trouble with it. Having to read doco to resize it was pretty not good for a newbie to linux. Has it improved since?
LVM does have a bit of a learning curve, but once you're over it, you realise how dumb it is to keep partitioning disks like it's 1995.
Most if not all graphical disk managers now work with LVM.
Thats good to know, thank you for that info, I might look into it next time i have to reinstall.
