Well, it didn't work (this to all the respondents).

I did change the group and mod of /etc/portage, but even before I did:

"sudo echo 'media-video/xine-ui ~x86' >>/etc/portage/package.keywords"
-bash: sudo echo 'media-video/xine-ui ~x86'
>>/etc/portage/package.keywords: Onbekend bestand of map

("unknown file or folder", which is at least different, but not really
much of an improvement, and no, before someone asks, putting a space
before /etc doesn't help)

and even after chowning and chmodding:

 sudo echo 'media-video/xine-ui ~x86' >>/etc/portage/package.keywords
-bash: /etc/portage/package.keywords: Toegang geweigerd

(permission refused)

with the quotes, it's unknown file or folder.

Not really sure what good the portage group was supposed to do anyway,
since root is a member of that group, but then again root owns the whole
shebang anyway. The user is not a member of the portage group.

Should I chown the folder -R to users? (seems again quite not the
point)? It still seems that what I really want is a login shell that I'm
not getting.

I'm really lost. Where am I going wrong?

Oh, btw, just remembered-- this is bash 3. Does that make a difference?
