            Bug ID: 242314
           Summary: newfs_msdos(8) -A option prevents using -o but usage
                    says incompatible with -r
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: guyyur@gmail.com

newfs_msdos prevents using -A with -o but complains on -A and -r

Doesn't allow -o but complains on -r
# newfs_msdos -F 16 -c 8 -o 8192 -m 0xF8 -A /dev/ada5s1
newfs_msdos: align (-A) is incompatible with -r

Allows -r
# newfs_msdos -F 16 -c 8 -r 2 -m 0xF8 -A /dev/ada5s1
/dev/ada5s1: 57248 sectors in 7156 FAT16 clusters (4096 bytes/cluster)
BytesPerSec=3D512 SecPerClust=3D8 ResSectors=3D2 FATs=3D2 RootDirEnts=3D512=
 Sectors=3D57344
Media=3D0xf8 FATsecs=3D28 SecPerTrack=3D63 Heads=3D16 HiddenSecs=3D0

Looking at the changes of D15672, I think -r should be blocked when -A is
passed so it should be checking
if (o.reserved_sectors)
   errx(1, "align (-A) is incompatible with -r");
instead of
if (o.hidden_sectors_set)
   errx(1, "align (-A) is incompatible with -r");
