Whenever I try to fetch a package through the emerge program, and FEATURES="userfetch" is enabled, wget fails to fetch the package due to "temporary resolver errors". I remove this feature and everything works as expected.

Works just fine here...
Create an strace log and attach it: strace -f -o strace.log emerge mplayer -f
Created attachment 114200 [details] strace -f emerge pkg -f I actually just reproduced the problem on a much smaller package because I didn't want to redownload it.. (although, I probably sh/could have just moved the package out of distflies.. oh well. Attaching the strace now..
13933 open("/etc/resolv.conf", O_RDONLY) = -1 EACCES (Permission denied) It's not able to access /etc/resolv.conf for some reason. Check the permissions on each path element and ensure that directories have a+rx and files have a+r.
(In reply to comment #5) > 13933 open("/etc/resolv.conf", O_RDONLY) = -1 EACCES (Permission denied) > > It's not able to access /etc/resolv.conf for some reason. Check the > permissions on each path element and ensure that directories have a+rx and > files have a+r. While this probably fixes the immediate problem, it doesn't address the bigger problem -- a user process circumventing the system resolver routines and trying to read /etc/resolv.conf directly. wget (and any other utilities I can think of) works just fine from a user account without read access to /etc/resolv.conf, and this is (yet another) nscd problem. Turn off nscd, and things will work fine again, without having to give the world read access to various /etc files they have no business reading. (And it will also fix lookup problems where you get your resolving through host files, nis and/or ldap without using a dns, and thus don't have to have a resolv.conf file at all) Have I mentioned before how nscd is evil and must be destroyed? :-)
chmod 0644 /etc/resolv.conf did solve the problem. I did not have nscd running at the time...
Ok, so the userpriv process needs access to /etc/resolv.conf either directly or through the nscd daemon. It's a system administration issue that portage can't really do anything about.
