yes, It appears I might be wrong

This warning is probably just a overly paranoid openbsd compiler
vac.c:509: warning: sizeof(pointer) possibly incorrect in argument 3

and might not be related to this error
create bsize 8192 psize 8160vac: vacfscreate: vacfileroot: read too
small: asked for 0 need at least 389

I looked at it again and tried the vac command on a test venti and it
worked with no errors. Even with the sizeof warning. I no longer have
a copy of the problematic plan9port.tgz so I took
a new copy from swtch.com. It was either fixed by someone else or the
error was a fluke.
