A shell script testing went bad and it issued
chmod -R 777 /.
to the system, instead of
chmod -R 777 ./
and as expected it wiped the critical meta data. We have turned off the system and it will not function properly the next time it is turned on.
I am told that
rpm --setperms -a rpm --setugids -a
should atleast fix the permission of the packages maintained by rpm. Is it worth doing?
And is there any script available which will copy the permission from an identical system? To atleast get the box working. The Box is running RHEL5.5
