4.4.3 Storing Key Un i x Files on a Second Disk
If you have two disks on your workstation, store a copy of the key Un i x files
on the second disk. You could boot from the second disk if the root file system
on the first disk became corrupted (see Section 4.5.4).
See Chapter 6 for a discussion of disk configuration. Note that it is not
possible to boot from a second disk that has been configured as a single file
system.
The procedure below assumes that the file system on the a partition of the
second disk is named /n. To store a copy of key Un i x files on the second disk,
follow these steps:
1. Change to the root directory:
cd /
2. Create a file that contains the key Un i x files. (The backslash in this
command is typed only when immediately followed by a
RETURN
as
is the case here):
find .cshrc .login .profile vmunix* bin etc dev \
-print -type f | sort > /keyfiles
The key Un i x files consist of:
•fivefilesfromtherootdirectory,
•allofthefilesinthe/dev directory, and
•someofthefilesfromthe/bin and /etc directories.
3. Edit /keyfiles to remove any files prefixed with bin and dev that are
not listed below.
bin/cat bin/chgrp bin/chmod bin/chown bin/cp
bin/cpio bin/csh bin/dd bin/echo bin/ln
bin/ls bin/mkdir bin/more bin/mv bin/ps
