With a UFS version from SunOS-4.0 (1987) or later, newfs of course and

If you want to enlarge cpg, with the same amount of total inodes in the file
system, you'll need more space for the inode bitmap in the cg superblock.
But the cg superblock is limited to one fs block.
So to use a larger cpg value you usually have to decrease the inode density.
This is what I said: The clean flag was always in (but unused).

SunOS-4.1 did introduce it around 1989.
FreeBSD did introduce an incomatible implementation after 1993..
Who cares. I already told you, that I had to fsck the filesystem anyway
before using it on the other system, so the fs_clean flag was irrelevant.
WRONG: Nothing did shift caused ny the shadow inode.
I said that they are on shifted locations. I didn't say that they were once
shifted on purpuse in the same implementation.
I have done it back these days several times. I used an UFS formatted ZIP
disk for data exchange between FreeBSD and Solaris/x86. It was far from
perfect, but it worked at least for regular files and directories. I didn't
have any intention for using more features.
If you did do the exchange between FreeBSD and an old Solaris version that
still did use ic_oeftflag, you may have had more luck then now.
Like I said: "Back these days". I also pointed out several times, that it
may not work with newer releases anymore.
But what is your point?
We all know that *BSD's and Solaris' UFS have subtle differences. I just
said, that I once was able to "ignore" these differences and was able to
read and write UFS file systems on the other system.
