This solu= tion is messy so I wanna try to avoid it.

Or alternatively, a better way to run a command as = root without password on user login, after sourcing ~/.profile? I do not have much experience with shepherd (yet!), but cannot you just use '("sudo" "mullvad-daemon" "-v")? While still requiring an entry in sudoers file, I would say it is cleaner than sudo ... in the ~/.profile, and it you could still start/stop it via the herd command. > =20 > Thanks! --=20 There are only two hard things in Computer Science: cache invalidation, naming things and off-by-one errors. --iY5mfNwpdm4+sV0/ Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEt4NJs4wUfTYpiGikL7/ufbZ/wakFAmTt8HsACgkQL7/ufbZ/ wal+pw//T/Xi9Egyhi/ssq9qKkxfkGe2b8UFZpar5H5byD6rQNeZ0bMKkaPVFjP5 P6lnVl3S40l2XBjyHuDpJVZ+o9gaP1r95GLPPNGL3imB0dmIwljcuRj/YV/fXvA0 /WPjphdztMTSFAUqI1AQXq7j01CVQ9aWA6riUp5TtYO0bNa7PqMJCi73xqmD654w JblTDdkcrSQWJFiKUWYmRDtGPD3BvvKrqpFL1szyWdRGrA5xKUj6GAWOj2qsCBhN M7VuTSy6xL0RONhFAR3KvFZh30R5zQbTf5MS86fCMHeIs3RQJ00k91DwqxWfR8/d 3yX9UBQ+rYczMl+2eQCwR6nes35Khfms1pd/oqYpNFpynQ4qKRMKy4ccOH84HeE+ zXx69tRBB/Jzhwn4H42FoQNm6gtWDynoxz4nf9O1SA/OaxZ7Sdu98LTfB1SV1Fgp Y3sUvlfL5iADpPt6TXURz4JMWY3TKgEOwWeHFzGVb+mCn/VYMyqn1BE1SEOQ6CSM mmrsYQMXIPzhPq/RCOad/zFH/USjs5JRF69AXYnxmJ6t97/Ey3hUmOZ9ogAaLNSi l7YYSP8zA5v4qxNZZCRa1y9y/bNjZn33lVWp4x1yfpnqisILD3HpdNKch+E/9pzh JWY7mraGgGWvP9IoN6zjpjMrGPsl2BG/M01iFAcEAeyMxm8/W6E= =sqZM -----END PGP SIGNATURE----- --iY5mfNwpdm4+sV0/--
