Do not use fexecve
Script executed via fexecve has a file descriptor number in argv[0]. This results in unexpected output: when displaying the script help, a user see Usage: <number> [options] instead of Usage: <scriptname> [options]. This can be demonstrated on mock:
$ rpm -q usermode
usermode-1.114-1.fc34.x86_64
$ mock -h | grep Usage
Usage: 6 [options]
$ dnf upgrade usermode
$ rpm -q usermode
usermode-1.114-2.fc34.x86_64
$ mock -h | grep Usage
Usage: mock [options]
