>Subject: [PATCH] 7675 New script for changing selinux file labels on perl scripts
>Content-Type: text/plain; charset="utf-8"
>
>On some Linux distributions like RedHat, Fedora, CentOS you can use SELinux for enhanced security. Among others, this involves file labeling (security context). In other distributions SELinux can be installed additionally.
>
>The attached script xt/set-selinux-labels lets you update and restore such labels on the perl scripts in a Koha installation.
