what is the current fss(4) status?

Hi,

I recently found out about fss/fssconfig to make ffs-filesystem
snapshots; it works very well for me. However, netbsd 4.0 fss(4)
manpage (from April 17, 2005) says "This driver is experimental.  Be
sure you have a backup before you use it.". Does that still apply? How
safe is it in practice?

Thanks in advance,
