I had trouble getting programs.firejail.wrappedBinaries to have any effect on my
system (#152852), because I did not realise that "put[ting] the actual
application binary in the global environment" included adding the program
package to environment.systemPackages, and I thought that the package must be
present for this option to take effect. I have added a clarifying parenthetical
statement explicitly mentioning environment.systemPackages in this caveat.
