No, you do not want to use *, you want to use . Remember that the shell |
| 20 |
expands "*" and you will be at the mercy of whatever happens to exist in |
| 21 |
that directory. Using * you will miss all "dot" files. Here's the |
| 22 |
command you want: |
| 23 |
|
| 24 |
tar czf /otherdisk/boot.tar.gz . |

Same as above, use "." not "*". |

Yeah, probably, but most times it's just as easy to just delete them |
| 46 |
after you've restored them. You're still booted from the CD after all.... |

In the perfect world, you'll be running fine from here. Let us know how |
| 53 |
reality compares, though! |
