Looking more closely I think the "statfs()" call was for SunOS 4.x, and
more recent Solaris versions use the "statvfs()" call.

/usr/bin/df also uses a statvfs-family function internally (at least on
the "SunOS 5.9" system I am able to test on)... so off hand it's not
obvious why amcheck would get different results than "df".
Still, there's a small chance that seeing the output you get from
df -v /var/spool/amanda/disk1 /var/spool/amanda/disk2
and
df -g /var/spool/amanda/disk1 /var/spool/amanda/disk2
could shed some light on what's going on with that call.
