How to install on a hard drive with plenty of space? Main drive running low!

[Greg]

Hi,

I don’t have a ton of space on my main drive because I decided to let the main drive be a SSD for faster startup. I have a external USB drive as the driver I want to install all my software on.

How do I tell snap to install software on the external drive?

have a look at:

How to place your snaps elsewhere than /var/lib/snapd

Hi There. I struggled with this myself, as i could not find any one clear guide with the requisite steps, so I thought I’d just show everyone exactly what I did to make it work. I want mine to be in /opt/snapd Please note, this was on Manjaro, but i see no reason it should not function elsewhere: (given the proper install command, of course) First, install snapd sudo pacman -Sy snapd Then disable snapd and snapd.socket services: sudo systemctl stop snapd sudo systemctl disable --now snapd…

The only issue I see would be that my drive is on a external USB and could switch locations at startup :/. … The computer I have only had room for 1 HD. It’s also a low profile type of system.

Yesterday it was /dev/sdb and today it is /dev/sdc1

grab its UUID and add it to fstab to mount it in a fixed place …

i.e. i have a big raid array on my desktop, imagine it mounts the drive in /mnt/drive, then i add a systemd mount unit to bind mount the snapd dir from there with:

$ cat /etc/systemd/system/var-lib-snapd.mount 
[Unit]
Description=Mount unit for snap packages
Before=snapd.service
After=local-fs.target

[Mount]
What=/mnt/drive/var/lib/snapd
Where=/var/lib/snapd
Options=bind

[Install]
WantedBy=multi-user.target
