Description David Heidelberg (okias) 2014-10-21 09:56:10 UTC 
Installing new software is completly fine.
But when I try unmerge/depclean anything (or portage want's remove slotted software), it ends like this.

Setup is: mounted / to /mnt/$hostname and chroot on it.
SW: ~amd64, latest portage, kernel 3.16.5 (anyway, this issue has been there for long time not depending on SW/Kernel)

# mount
pc:/ on / type nfs4 (rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,local_lock=none)


# emerge --depclean -av ktorrent
