This is due to FS bogons. There are two bogons in action:
(1) 'async' isn't really fully async. Directory creation is still
done synchronously.
(2) The directory inode layout algorithm is not really efficient for
things like the ports collection.
There are a number of solutions available:
(1) Change 'make release' to scan the ports collection and create an
mtree file beforehand; apply the mtree file before extracting the
collection. This will make the inode layout more efficient.
(2) Change the directory inode layout policy in the kernel to a more
efficient scheme
(3) Hit jkh with a baseball bat until he stops refusing to use soft
updates on the boot floppy during install (due to "making a point")
(4) Fix the async code so it actually is fully async
1 and 2 are alternate solutions to the same part of the problem; 3 and
4 are alternate solutions to another part of the problem. Solving any
of these would be useful, but solving one problem from each group
would give most benefit.
