Follow up to r290259 dealing with makefs(8)
- Don't use contractions (don't -> do not)
- Change "throw away" to "discard" when describing the -o keep-bad-images option
- Revert author e-mail split I brought over from NetBSD, effectively reverting
the change bapt made in r267668

r289203 (by adrian):
makefs: introduce a new option to specify what to round the resulting
image up to.
From ticket:
While trying to run FreeBSD/mips on some device having very small flash media,
one is forced to compress file system with mkulzma(8) utility. It is desirable
to specify small UFS block/fragment sizes like 4096/512 bytes for makefs(8)
and big compression block size like 65535 bytes to mkulzma at the same time.
Then one obtains very good comression ratios (like 75% and more) but faces
the following problem.
geom_uncompress kernel module reports GEOM provider size rounded up to its
compression block size. Generally, this changes original media size and now
it fails to match the size of embedded UFS file system that leads to other
problems, f.e. geom_label kernel module does not like this and skips the
file system while tasting the GEOM and looking for UFS label.
This makes it impossible to refer to the file system using known UFS label
instead of something like /dev/map/rootfs.uncompress.
The following patch introduces new command line option "-r roundup" for makefs
that makes it round up the image to specified block size. Hence, geom_uncompress
does not change GEOM media size for images rounded that way and geom_label
accepts such GEOMs just fine.
With the patch applied, one can use following commands:
$ makefs -t ffs -r 65536 -o bsize=4096,fsize=512,label=flash optimization=space fs.img fs
$ mkulzma -s 65536 -o fs.img.ulzma fs.img

r290180:
Follow up to roundup feature addition in r289203
- Rename -r to -R to avoid the clash with makefs -r in NetBSD
- Note that -R is an FFS-specific option because it's not implemented
in cd9660 today
- Rename the roundup variable to "roundup-size" in the manpage and help
text for consistency with other variables.
- Bump .Dd (missed in r289203)

to be created. The support is based on mtree version 2.0, as used
in libarchive, but adds new features on top of it.
The current implementation is fully functional, but is envisioned
to grow at least the following additional features over time:
o Add support for the /include special command so that manifest
files can be constructed using includable fragments.
o Add support specifying a search path to locate content files.
o Content file filters: commands that provide file contents on
stdout.
The manifest file eliminates the need to first construct a tree
as root in order to create an image and allows images (releases)
to be created directly from object trees and/or source trees.
