Re: Debian 13, tmpfs and /tmp, /var/tmp

Indeed, /tmp is already on tmpfs. Isn't /var/tmp supposed to be as well now?

Is this tutorial still accurate?

Thank you for your help!

Hello everyone,

I have recently installed Debian 13 KDE Plasma, but due to the advanced installation needed to set up @ and @home sub-volumes in a btrfs partition, my /etc/fstab doesn't include the new tmpfs lines concerning /tmp and /var/tmp. Are these the correct directories? Are there others?

Could you send me the new tmpfs lines in /etc/fstab? I don't want to improvise and mess up my system...

Thank you!

This is not needed in the /etc/fstab as it should be handled by systemd.

Check to see if it isn't already mounted.

$ mount|grep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,size=32875324k,nr_inodes=1048576,inode64)


Check the system log:


$ sudo journalctl -b0|grep /tmp
Aug 19 05:08:36 tas systemd[1]: Mounting tmp.mount - Temporary Directory /tmp...


Cheers,

Historically, /var/tmp has never been mounted using tmpfs. The forum post referenced is from 2011 and was still using rc init scripts.

The script referenced was a user created script to accomplish the /var/tmp mount.

As long as I can remember (SunOS 4.0), /var/tmp was always a regular file system.
