Hehe, agreed!  Back in 2006 I flew out to San Francisco to install a 
file server (NFS, AFP, SMB.....on Solaris 10 x86).  I came back 10 
months later not sure what I'd find and....;
# uptime
  10:10am  up 297 day(s), 16:56,  1 user,  load average: 0.23, 0.05, 0.02

I save it for posterity.

At the time there wasn't snapshot ageing for ZFS but I'd written 
something that allowed for that and not only was the server running fine 
(zero maintenance)
the ZFS snapshot backups (a months worth) were as well.

While I know a lot of developers who don't like Solaris, luckily we 
still have many SPARC and x86 Solaris 10 boxen here at $client-job-1;  
they tend to just run and run. I lost track of the longest uptime but I 
think it was 400+ days.

I agree with you Eric...I think ZFS is the best filesystem since sliced 
bread.  We had a box that failed two drives (raidz2) and ZFS kindly 
reported that we should restore two specific files from tape and install 
two drives...then the server kept running happily along.

I think if one were to build a home file server for archiving a music 
collection, it would be hard to do better than ZFS...the only thing that 
offers bitwise data integrity/checking. FreeNAS it all the easier.
