Description Andreas K. Hüttel archtester

from the fakeroot man page: "Every command executed within fakeroot needs to be linked to the same version of the C library as fakeroot itself."

glibc was recently updated, and I have FEATURES=fakeroot set, which may explain why I am suddenly unable to complete emerge -eav world (random hangs without cpu usage).

testing now with FEATURES=-fakeroot set

(another possible cause for the hangs might be bug 487558)

given the manpage, my suggestion would be that
* either the sys-libs/glibc ebuild outputs a fat warning on update if FEATURES=fakeroot is set
* or that portage detects a glibc update and warns

actually the hangs seem to be unrelated to fakeroot. :( 

doesn't change the thing about the manpage instructions, but the issue is probably not so serious. 

I'm closing the bug, reopen if you still want to act on it.
