 Log Message:
 PR/52828: Mark Johnston: makefs UFS2 lazy inode initialization is buggy
 
 makefs(8) emulates UFS2 in performing lazy initialization of inode
 blocks when allocating and writing inodes. However, it only ever
 initializes one inode block at a time, which may be insufficient.
 If so, a later initialization may clobber an inode, resulting in
 an inconsistent filesystem.
 
 I committed a minimal fix for the problem to FreeBSD:
 https://svnweb.freebsd.org/changeset/base/326912
