    Rel 4; make cronie restart itself when PAM problems happen.
    
    On glibc/pam upgrades cronie can be very unhappy:
    
    Feb 9 13:52:01 firma /usr/sbin/crond[6592]: (root) FAILED
    to authorize user with PAM (Moduł jest nieznany)
    
    because crond is inked with old stuff and can't dlopen newer pam modules.
    
    Exact cause (like which symbol) is not known because crond
    is using PAM_SILENT flag which silences most of pam error messages.
    
    Add hacky script to make crond self cure (this problem happened way
    too many times for me).
