Re: editing /etc/sudoers

[John Soo <jsoo1@asu.edu>]

Hi Jeff,

Sorry this is so confusing. Let me know if I’m missed something since I’ve been half-following this thread. I think what you may want to do is use the sudoers-file field when specifying your operating system rather than using visudo to edit the file. This way you will have persistent and declarative specification for the sudoers file. The sudoers-file field allows you to place an arbitrary file-like object in it, so you can put whatever you want to add using visudo there and it will work the same. Check the manual for reference: https://www.gnu.org/software/guix/manual/en/html_node/operating_002dsystem-Reference.html#operating_002dsystem-Reference

Hope that helps,

John
