What do you think?  Is it worth it to try building Linux
on a ramdisk?

6.8.7 is out now, so I thought I'd try it:

$ time -p make -j 32
[...]
real 432.09
user 11085.32
sys 2520.37

That's with a "kitchen sink" build using a .config that
originally came from Linux Mint's "lowlatency" sources.

(To set it up, I unpacked the tar file onto /dev/shm -- much
faster than if I'd tried to rsync the unpacked sources.)

After the build:
$ df -h .
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           126G   23G  103G  19% /dev/shm

(Of course, now that I've done this stunt, I'm rsync'ing
the tree onto my NAS, so I'll have it after the reboot.)

And there you go: doing Linux stunts, so you don't have to.
