Wait'll you guys hear about buying more RAM and using it as a RAM disk.

Woah. Next you'll tell me I could increase the dimension size of my punchcard, to store more upon.

  You can store twice as many puns on a 16" punchcard.

I have more RAM than I need, and just the other day I set up a RAM disk to put my /tmp directory on. My comic reader unpacks huge rar and zip archives into /tmp at every run, and I don't want it to wear out my SSD. I put this line in /etc/fstab: none /tmp tmpfs defaults,size=4G 0 0 It works like a charm. And in the worst case, if I run out of RAM anyway, it readily swaps out.

  This is a commonly recommended thing to do! It helps IPC performance in some ways - also makes sure nothing in there persists longer than intended. You might consider these common mount options for a little extra security: noexec,nosuid,nodev (and potential headaches, to be fair) While /tmp is a great world-writable place, these restrict it from being home to executables/devices -- common sources of abuse

    Thank you for the tips! It was just a quick hack and I never knew much about the mount options, but I guess it's time to learn.

      Certainly! I picked these up through some compliance benchmarks, commonly applied to /tmp -- I'd exercise caution with these elsewhere, they're fairly restrictive

  You could also do https://wiki.archlinux.org/title/Firefox/Profile_on_RAM https://wiki.archlinux.org/title/Firefox/Profile_on_RAM , or more generally https://wiki.archlinux.org/title/Profile-sync-daemon https://wiki.archlinux.org/title/Profile-sync-daemon or https://wiki.archlinux.org/title/Anything-sync-daemon https://wiki.archlinux.org/title/Anything-sync-daemon Or just skip that install to media stuff altogether, and run from some live distro booted into RAM, and running from there :-)
