OpenBSD's doas on Voidlinux

The rationale for sudoedit is that text editors are complex programs that could cause damage if given unchecked root access. As such, it’s better to use the cp command to copy the file so that a non-root user can edit it, run your editor as a non-root user to edit the file, and on exit run cp to overwrite the original file with the user edited file. To make a sudoedit with doas, you can make a wrapper copy files around.

However, if you use emacs, you can easily create a sudoedit replacement for doas. TRAMP for emacs supports doas. As such, I add the following to my .bashrc:

doasedit(){
    emacsclient -nw /doas::${1}
}

Running doasedit <filename> now allows you to edit the file like sudoedit!

On Voidlinux, sudo is part of the base-system group. If we want to remove sudo, we must tell xbps that sudo can be substituted by doas.

To substitute doas for sudo, I edited /etc/xbps.d/99-my-settings.conf and added:

virtualpkg=sudo:opendoas

See man xbps.d for more details on the virtualpkg keyword.

To remove sudo, we can now run:

doas xbps-remove sudo
