[ClusterLabs] /etc/profile.d/which2.sh bug in RHEL/OL 8.5 can impact shell scripts

[Hayden, Robert]

Just an FYI - there is a bug[1] in /etc/profile.d/which2.sh script that can cause ksh scripts to fail.   This impacted a Cluster when I upgraded to Oracle Linux 8.5.  We have a custom resource that calls a ksh script.  Within that ksh script we were sourcing /etc/profile.   This in turn, sources the /etc/profile.d/which2.sh script.   The which2.sh script returned an error that cascaded back through our Cluster Suite resource shell script causing the node to evict.   I downloaded Red Hat's proposed fix and that resolved my ksh script issues.   I am hoping that Red Hat releases the correction for RHEL 8.5.

Unsure if others may get impacted, but I thought I would bring it up to the community.

Thanks
Robert
