* MFC r269953:pfg2014-08-161-1/+1
| | | | | | | | | | | | | | Use "NO NAME" as the default unnamed label. Microsoft recommends avoiding the use of spaces in the string structures for FAT. Unfortunately they do just that by default in the case of unlabeled filesystems. Follow the default MS behavior to avoid confusion in common tools like file(1). This was actually the default behavior before r203868. Obtained from: NetBSD (CVS rev. 1.39)

* Some useful operational extensions to newfs_msdos, especiallyluigi2008-12-031-8/+100
| | | | | | | | | | | | | | | | | | | | | | | | | when preparing images for emulators or flash devices: + option '-C size' to create the underlying image file with given size. Saves doing a 'dd' before, and especially it creates a sparse file + option '-@ offset' to build the FAT image at the specified offset in the image file or device; + make the cluster size adaptive on the filesystem size. Previously the default was 4k which is really unconvenient with large media; now it goes from 512 bytes to 32k depending on filesystem size (i still need to check whether it makes sense to go further up, to 64k or above); + fix default geometry when not specified on the command line, use 63 sectors/255 heads by default. Also trim the size so it exactly a multiple of a track, to avoid complaints in some filesystem code. + document all the above, plus some manual page clarifications. MFC after: 4 weeks

This way you can a FAT image on a file as simply as this: newfs_msdos ./some/file (right now you need a much longer command newfs_msdos -h 32 -u 64 -S 512 -s $total_blocks -o 0 ./some/file Will be merged after 7.1 and 6.4 are released.
