Hi,
I use certificates from let's encrypt for my website and mail servers,
and found that there was an issue with certificates generated by the
certbot service in Guix: the generated private keys are world-readable
(in a directory that cannot be accessed by anyone but root, so it's OK I
guess). OpenSMTPD is not happy with that though, so I have to chmod the
files every time. I came up with a variant of the deploy-hook that's
presented in the manual, and I'd like to update the example with it.
Here it is:
;; Find running nginx and reload its configuration (for certificates)
(define %my-deploy-hook
(program-file
"my-deploy-hook"
#~(let* ((pid (call-with-input-file "/var/run/nginx/pid" read))
(cert-dir (getenv "RENEWED_LINEAGE"))
(privkey (string-append cert-dir "/privkey.pem")))
;; certbot private keys are world-readable by default, and smtpd
complains
;; about that, refusing to start otherwise
(chmod privkey #o600)
(kill pid SIGHUP))))
What do you think?
