Managing filesystem types

Mounting filesystems from a diskette

It is common for small filesystems to be contained completely on a single floppy diskette. You can define filesystems on diskette and use them either for storage or for live access. Using a diskette (rather than a hard disk) for live access has the following two disadvantages:

It is slower.
It ties up the diskette device.

It is common for users to copy a filesystem on a diskette to a directory on a hard disk. To do that, the filesystem must first be mounted. A user who plans to establish a filesystem that can be brought in from diskettes first needs to create two directories on the hard disk:

one to serve as a mount point for the floppy disk
one to be the root directory of the filesystem being brought in.
To copy in this way:
1. Create the appropriate directories. The mount point is named /mnt; the root, /myfs.
2. You can then copy an s5 filesystem from diskette to hard disk with the following command sequence:
```
   mount -F s5 -o ro /dev/dsk/f0t /mnt
   
   cd /mnt
   

   find . -print | cpio -pdm /myfs
```
  where -o, followed by the argument ro, means read-only.
  See find(1) and cpio(1) for an explanation of the other options used.
