Any use for an NSLU2 device?

Now I work as a software engineer and because of the covid-19 lockdown I am spending even more time in front of computers at home and I thought that – finally – this was the moment to make proper use of the NSLU2 NAS decvice I bought more than a decade ago.

But it turns out that this supports a now dead version of Samba/CIFS so isn’t much use. So, I thought, flash the thing and use one of the various FOSS options, but these seem to be either dead or close-to-dead these days.

So is there any way I can get decent use out of this device?
