today I ran into a strange problem. Both the root file system and the /home filesystem showed 100% usage:
df -l
Filesystem 1K-blocks Used Available Use% Mounted on
devtmpfs 4096 0 4096 0% /dev
tmpfs 32793004 0 32793004 0% /dev/shm

/dev/nvme0n1p7 487160 14280 472880 3% /boot/efi
tmpfs 6558600 196 6558404 1% /run/user/1000
tmpfs 6558600 88 6558512 1% /run/user/0
When I did a du -s of my home directory it showed only 96GB used.
sudo du -s /home/*
96910360 /home/pgaltieri
The problem turned out to be a large file in /usr/local. When I removed this file both / and /home dropped in their usage:

tmpfs 6558600 204 6558396 1% /run/user/1000
so why are / and /home the same device? In the past / and /home where separate devices. This is for F31
