@retnag
It should just work, maybe a reboot is required, idk for sure.
But in order to use nullfs in /etc/fstab you should add nullfs to /etc/mkinitcpio.conf MODULES:

MODULES=(nullfs)

And re-create the ramdisk off cause:

mkinitcpio -P

Am I missing something? After installing the package, I can't use nullfs.

sudo mount -t nullfs none /var/log/hugefiles                   
mount: /var/log/hugefiles: unknown filesystem type 'nullfs'.
       dmesg(1) may have more information after failed mount system call.

I tried running modprobe nullfs like it says on the README, but again, the module can't be located.

I also tried mounting via fstab: none /nullfs nullfs auto - same error.

Are there extra steps besides building and installing, that we need to make?

Build of the DKMS module fails because warnings are treated as errors:

[...]

cc1: some warnings being treated as errors

The option -Wno-error should be added somewhere
