I'm trying to figure out how to work around `gpgconf` complaints in T4866, so i thought i would look into using `gpgconf` itself to see whether it was safe to run a program if the home directory doesn't exist. `--check-programs` seems like the obvious choice, but the results are surprising:
0 dkg@alice:~$ HOME=/nonexistent gpgconf --check-programs
gpgsm:S/MIME:/usr/bin/gpgsm:1:0:::can't create directory '/nonexistent/.gnupg'%3a No such file or directory:
:::::::keyblock resource '/nonexistent/.gnupg/pubring.kbx'%3a No such file or directory:
This raises several questions:
- what does the line between `gpgsm` and `dirmngr` mean? Is there documentation to tell me that i should expect some line with empty values in first 7 fields?
- the `avail` field is `1` (true) for all of them, meaning "installed and runnable" according to `gpgconf(1)`, bug in T4866, @werner says: "GnuPG requires its home directory". Which is correct?
- Why do `gpg-agent` and `gpgsm` both have `okay` ("config file is syntactically ok") set to `0` (false), but the others claim an OK config file in the same situation?
