I need your help.

I'm wracking my brain in order to understand how tmpfs works.

I have a thin client machine whose o.s is Suse Linux.

If I get access to the system through admin user and create a file in /home/admin/Desktop after reboot the file is still there.

But if I create a file in /usr/lib/cups/filter after reboot the file is gone. Of course you would say if the file system is tmpfs nothing might sound strange. Right, but why does the file created in /home/admin/Desktop gets preserved after restart?

mount command shows:

tmpfs on / type tmpfs (rw)

proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)

devtmpfs on /dev type devtmpfs (rw,mode=0755)

tmpfs on /dev/shm type tmpfs (rw,mode=1777)

devpts on /dev/pts type devpts (rw,mode=0620,gid=5)

usb on /proc/bus/usb type usbfs (rw)

Is there a way to get files permanently saved in /usr/lib/cups/filter after reboot?

How do things work?

thanks a lot

Your machine does not have a disk! Because of this, you cannot save anything to it permanently.

You can only save to /home because it is a remote filesystem exported from another computer.

  • The list of mount points in the question does not include /home, which means something does not quite add up. It is however likely that some information is missing in the question, and your guess turns out to be entirely correct anyhow.

  • @kasperd I guess that it's either automounted, or the OP intentionally omitted it.
