The future of 32-bit Linux

On the other hand, home firewalls are often drop-in boxes that don't really need to follow upgrades when there is zero exposed service running on them. Mine runs on a 2002-era VIA-Eden i586-like CPU with a 2.4 kernel last built in 2010... it will eventually be replaced but migrating rules is a pain when everything works fine out of the box. I'll probably wait for the hardware to die.
