And everyone who has emacs has to do extra work too, in order to get sudo to respect their chosen editor. Changing the default fallback for visudo when the environment variable isn't defined will add in further dependencies and/or put a dependency on a package that can't be reasonably assumed to be on the system in the near future. You're not being forced to do more work because you use vim, you're doing more work because you remove the sane default editor from the system. As does everyone removing nano and using pico.... and... how many others? Go to LFS, build it all, build emacs, set EDITOR to emacs, and run sudo visudo. Please. I have a rather good guess that you'll be, amazingly, using the default that was set at build time for the sane default editor, in LFS's case vim (whether called by that or the vi symlink to it), that the distro creators chose. Or if you vary from the instructions, choosing some other editor at sudo's build time, you'll be running that. The ebuild does the logical thing in choosing an editor that a) is in place by default and b) is less likely to be on the system or off the system by the admin's whim. Most leave the default in place. I suppose, really, the only more guaranteed editor would be "busybox vi" ... because VERY few go about breaking the default tools built into busybox... but what would that leave the many who use nano by default, as... it IS the distro default, to do? Compared to nano, vi (let alone a bare minimal vi like is in busybox) is a pain to use for a person who's never seen it before. Also, randomly, I could be wrong here, not being a sudo user myself outside of my ubuntu laptop... but if you look into sudo ... it drops the environment, aside from those chosen specifically to be preserved by root, through its configuration, as a security measure. It's not an ebuild problem, it's not a 'defaults' problem. From what you seem to see as 'proper' behavior for sudo, it's an upstream security decision problem. -- Poison [BLX] Joshua M.
