/etc/conf.d/net

net is needed only if you are going to boot gentoo using loader.o or flashed custom kernel.

Cleaning portage

  1. cd /usr/portage
  2. rm -r `gawk '{ printf(”%s ”,$2) }' /etc/portage/rsync_excludes`

Testing

  1. USE=unicode emerge links

chrooting

If you have exited from chroot environment after installing gentoo chroot or if you have rebooted your DSM-G600 then you need following commands to enter back in chroot environment.

  1. mount -o bind /dev /mnt/HD_a2/gentoo/dev
  2. mount -t proc none /mnt/HD_a2/gentoo/proc
  3. /mnt/HD_a2/chroot /mnt/HD_a2/gentoo /bin/bash
