Fedora adapt

[jimc]

2 patches here:

1- use YAML.unsafe_load to avoid ruby 3.2 / Psych 4 error

in `find': Tried to load unspecified class: Time (Psych::DisallowedClass)
        from /usr/share/gems/gems/psych-5.0.1/lib/psych/class_loader.rb:28:in `load'

2- use single-quotes around grep 'pattern' since no variable interpolation is done. Maybe wrong wrt escape-backslash, I had no success proving it either way.
