OpenBSD Snapshots

How OpenBSD Snapshots are built:

In each snapshot, all tar.gz files are rooted at /. If you are a trusting kind of person you can use the following script. However it is suggested that you not blindly install snapshots in this fashion.

	foreach i ( `pwd`/*.tar.gz )
	    ( cd /; tar --unlink zxvpf $i )
	end

The tar program you use must be GNU tar, OpenBSD tar (based on pax) or some other newer posix-compliant version. The tar files contain directory information in a new format, in particular dev.tar.gz contains all sorts of files that an older version of tar would break on. Also, one should be able to use just about any version of pax instead.
