But it is still a good idea to configure it in the core. Some "rescue-disk" programs will use it, and
There are still many CIDS that may use the minix file system, because the minix file system is the most
Okay. At the beginning, Linus wrote the Linux

/Dev/hda3 on/usr type ext2 (defaults)
None on/proc type proc (defaults)
/Dev/fd0 on/mnt type msdos (defaults)
Take a closer look at each line. The word after "type" is the format of the file system. In this example
