Package: apt Version: 1.1.3 In apt's `apt-key` script (cmdline/apt-key.in), there are multiple calls to the external program `which`, which is often supplied by the `debianutils` package on Debianish systems. However, apt's control file (debian/control) doesn't claim it to be dependent on the package. `apt remove debianutils` also doesn't prepare to remove `apt`, so there aren't any indirect dependencies either. A fast check on the script itself indicates that all `which` calls are used to determine the existence of certain commands like gpg, gpg2 and wget, and the output is discarded. Therefore, replacing all those `which` with `type` (XSI) or `command -v` (POSIX) is perfectly fine and dash-compatible. This also gives a trivial performance boost due to reduced calls to external programs. -- Regards, Arthur2e5 (0x222D7BDA)
