At the end of emerging alsa-driver I got the following message:
xargs: warning: a NUL character occurred in the input. It cannot be passed
through in the argument list. Did you mean to use the --null option?
rmdir: //lib/modules/2.6.20-ck1-sa6/kernel/sound: Directory is not empty
>>> media-sound/alsa-driver-1.0.14_rc2-r1 merged.
The resolution is trivial:
that's because of a missing option of xargs in the last line of the ebuild.
Either xargs -0 or xargs --null should be used after piped find -print0.
All the 1.0.14 ebuilds and version 9999 are affected.
