CentOS:/etc/grub.conf

2. Copy the/etc/rc.d/init.d/functions file to the/tmp directory, and add a # to the beginning of the line beginning with a blank character for each line of/tmp/functions with the find replacement command; The original whitespace character is reserved;

3, replace the/etc/sysconfig/init in/tmp/functions file is/var/log;

4. Delete the beginning of the line in the/tmp/functions file so #, and # followed by at least one blank character #;
