I'm with you, especially the forget bad blood part. I did my time in
big storage and I will no doubt do it again, but right now, what I care
about is bringing truth and beauty to small storage, which includes
that spinning rust of yours and also the cheap SSD you are about to
run out and buy.

I hope you caught the bit about how Tux3 is doing really well running
in tmpfs? According to my calculations, that means good things for SSD
performance.

Regards,

Daniel
