-[[!meta title="Problems with root-owned gpg keyrings"]]
-
-`/var/lib/monkeysphere/gnupg-host/` is root-owned, and the public
-keyring in that directory is controlled by the superuser.
-
-We currently expect the `monkeysphere` user to read from (but not
-write to) that keyring. But using a keyring in a directory that you
-don't control appears to trigger [a subtle bug in
-gpg](http://bugs.debian.org/361539) that has been unresolved for quite
-a long time.
-
-With some of the new error checking i'm doing in
-`monkeysphere-server`, typical operations that involve both keyrings
-as the non-privileged user can fail with an error message like:
-
- gpg: failed to rebuild keyring cache: file open error
-
-Running the relevant operation a second time as the same user usually
-lets things go through without a failure, but this seems like it would
-be hiding a bug, rather than getting it fixed correctly.
-
-Are there other ways we can deal with this problem?

-Here is an example when using monkeysphere-server
-add-identity-certifier on a host with a newly-installed monkeysphere
-installaton. Note that running the same command a second time works
-as expected:
