As I wanted to give 0777 permission for /home/test directory, I want to
execute "chmod -R 0777 /home/test", but I mistakenly executed "chmod -R
0777 /". Due to this entire file system permission got changed to 0777.
I am using Debian Linux 2.6.12
Now I am not able to execute su, which gives me error as "setgid:
Operation not permitted". It seems to be I have created a serious
problem. Can anyone please help me to solve this problem?
