@Andras,

Great point! SELinux can definitely cause unexpected issues if the right context isn’t set – especially on RHEL-based systems.

To make it permanent, consider using semanage:

semanage fcontext -a -t bin_t /root/scripts/conup.sh  
restorecon -v /root/scripts/conup.sh

If you're using RHEL, don’t forget about SELinux contexts - they can block scripts from running if not set correctly. For example, to allow your script to run, use:

chcon -t bin_t /root/scripts/conup.sh

This sets the correct SELinux type (bin_t) so the system treats it like a regular executable.
