This button changes the permissions of +/usr/bin/klaptop_acpi_helper from "0755 root.root" to "6755 root.root", +and therefore grants all regular users extra power management abilities. +This has obvious security implications, and should not be done on any +system where all users are not trusted absolutely. + +The standard klaptopdaemon changes the binary's permissions using chmod. +However, if an updated version of the Debian klaptopdaemon package +were then to be installed, it would reset the permissions, forcing the +sysadmin to reconfigure after each upgrade. + +The Debian package has therefore been patched to use dpkg-statoverride to +permanently change the permissions of /usr/bin/klaptop_acpi_helper. The +override is removed and permissions reset if the package is removed or +purged. However, if the sysadmin wishes to remove the special permissions +of /usr/bin/klaptop_acpi_helper, they can do so at any time by issuing, +as root, the following commands: + +dpkg-statoverride --remove /usr/bin/klaptop_acpi_helper +chown root:root /usr/bin/klaptop_acpi_helper +chmod 0755 /usr/bin/klaptop_acpi_helper |
