Maybe the last time you made symbolic links you really put them somewhere else, such as in /root. Try again making them with, say, cd / ln -s /mnt/hda5/var ln -s /mnt/hda5/tmp ln -s /mnt/hda6/usr ln -s /mnt/hda6/home and verify that these commands did what you wanted. For example, after the symbolic links are present you should find libncurses.so.5 in /usr/lib. By the way, one way people sometimes make their system less vulnerable to certain types of exploits is to make /usr readonly by mounting it on its own partition and mounting the partition readonly. You cannot do that with /home and /usr in the same partition. Steven Yellin On Sat, 26 Feb 2005, bj wrote: > > > -----Original Message----- > From: Steven J.

Thank you for the prompt reply. 80 % of the solution worked . Once I cd / and give the four link (ln ) commands three work . The result running file command on the links :- usr: symbolic link to /mnt/hda6/usr tmp: symbolic link to /mnt/hda5/tmp But the link to var didn't . It gives no error message. But when I type reboot , it shows that it could not find a file shutdown.pid under /var . Once I reboot , it gives quite few error messages that shows that it could not still find /var. It does stop around 5 minutes trying to start the system logger & after 5 minutes , it keep boots successfully. After I log in I notice a /var directory has been created . This /var has been created auto , as I didn't create it . The system is auto creating this directory & removing the sym link ,and so it does not find the other needed files in /var. Why do you think this is happening ? In addition I would also like to have the command to mount a partition read only . Cheers, bj When I do ls -lR , it gives out the ff contents :- var: total 4 drwxr-xr-x 3 root root 4096 Feb 27 09:28 lib var/lib: total 8 -rw------- 1 root root 512 Feb 27 09:28 random-seed drwxr-xr-x 2 root root 4096 Feb 27 09:22 rpm var/lib/rpm: total 308 -rw-r--r-- 1 root root 8192 Feb 27 09:22 __db.001 -rw-r--r-- 1 root root 1310720 Feb 27 09:22 __db.002 -rw-r--r-- 1 root root 360448 Feb 27 09:22 __db.003 -rw-r--r-- 1 root root 12288 Feb 27 09:22 Name -rw-r--r-- 1 root root 12288 Feb 27 09:22 Packages -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
