Hi Owen,

I think maybe disk size snuck up on us while we weren't looking. I
seriously thought my OS (Void Linux in this case) was using 4GB, but in
response to your post measured:

====================================================
[root@mydesk /]# du -h -s /usr
24G     /usr
[root@mydesk /]#
====================================================

I have the usual suspects installed: Libreoffice, Vim, emacs, Firefox,
Chromium, Openbox, LXDE, and a whole bunch of smaller stuff I've
installed over the years.

I'd be very surprised if a server-only system with LXDE/Openbox got
past 10GB, but programs are apparently a lot bigger than they were six
years ago, when I was routinely installing in 5GB.

I don't know whether you have a laptop or a desktop, or whether your
root partition is on SSD or spinning rust, but either way, disk space
is getting pretty cheap. 1TB SSDs are under $100 now, so you could have
320GB for / and the rest for other stuff. With SSD it's important never
to get too close to filling the drive, or you start repeatedly writing
on a small subset of the SSD.

If you're using spinning rust, you could use 160GB for /, and probably
wouldn't need to enlarge it for a few years. You can get Western
Digital Blue 4TB for just over $100. You can get even more bang for
your buck if you go Seagate, but I don't do that.

Unless there's something I'm missing, I'd advise just being generous
with your root partition, assuming /usr is on the root partition.

By the way, for the past 5 years I've had great success with using a
256GB SSD as my root partition, and putting all my big data files on
mounted spinning rust. My programs from /usr/bin load lightning fast,
but all told I have over 3T.
