Heya guys.. It's been a good 4 years with my SheevaPlug. I got my SheevaPlug for Christmas 2009. It's been running 24/7 ever since, as my fileserver (NAS), webserver, and firewall. I used the same 8gb SD card the whole time, though I managed to fill it all the way up a year or two back and have been kind of cramped ever since.
I just wanted to thank everyone here for the great help. Especially cbxbiker61 for continuing to release pre-compiled kernels for the unit, I upgraded several times along the way and it was always a relief to have a kernel that Just Worked.
In the end, I'm retiring it because I wanted to play with something new. My new server is a budget PC running FreeBSD.
If anyone would like my Sheeva, let me know.
