asterisk users - Jan 2022 - extensions.conf asterisk 18.8.0 question

If you're on RHEL or CentOS or one of its descendants, I would check if
SELinux is enforcing (`sestatus` or `cat /etc/selinux/config` and look for
"SELINUX=enforcing"), if it is, you'll probably need to create a
policy to allow the Asterisk context to execute rm and/or delete files.
I use `audit2why` and `audit2allow` in policycoreutils-devel (on CentOS) to
generate SELinux policy modules.

Oh, now that reminds me that those systems also tend to alias "rm" to
"rm -i",
so they won't delete files without confirmation.

Irritating in general IMHO, but it might be the cause of your puzzlement...
