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:
