How to expand /tmp from 1.9 GB to 2.5 GB

TravelerOS · 2025-10-12 21:11

While creating TravelerOS 4, I noticed that there is not enough space in /tmp to create the 01-core.sb file. The file was too large for /tmp to handle. Is there any way to expand the /tmp directory?

Yes, you need to edit /etc/fstab and just remove /tmp line. Reboot afterwards.

It still says that it's 1.9 GB.

Please post your /etc/fstab here and output of the commands:
$ mount
$ df -h

Run command:
$ sudo systemctl mask tmp.mount
Reboot and post back the result

It's no longer 1.9 GB, thanks!
