===''Exporting Your Remote Mounts with NFS''===


* On your target system we must setup our directories to be network exported to the host system.

{{file|name=/etc/exports|desc=NFS file systems being exported|body=
# /etc/exports: NFS file systems being exported.  See exports(5).
/      192.168.0.0/24(insecure,no_root_squash,nohide,rw,sync,no_subtree_check)
/boot/ 192.168.0.0/24(insecure,no_root_squash,nohide,rw,sync,no_subtree_check)
/dev/  192.168.0.0/24(insecure,no_root_squash,nohide,rw,sync,no_subtree_check,fsid=77)
}}

===''Mounting Your NFS Exports Locally and Binding Pseudo Filesystems''===

* We must then mount our exported directories on our host system and bind mount our pseudo filesystems.

{{console|body=
###i## mount foo.local:/ /mnt/piroot
###i## mount -t proc /proc /mnt/piroot/proc
###i## mount --rbind /sys /mnt/piroot/{sys,dev} 
###i## mount --make-rslave /mnt/piroot/{sys,dev} 
###i## mount -t devpts none /mnt/piroot/dev/pts
}}

{{note| 
You can safely ignore setting up NFS exports and mount the target filesystem locally with an sdcard reader if you desire. Mounting over NFS just makes for a more versatile setup without the need to transfer sdcards.}}

{{tip|
(For Better Performance!) mount a tmpfs on top of /mnt/piroot/var/tmp/portage
{{console|body=
###i## mount -v -t tmpfs -o size=8G,mode=775,uid=portage,gid=portage,nr_inodes=0 tmpfs /mnt/piroot/var/tmp/portage
}}

}}

==''Local Configuration''==

===''Editing make.conf''===

* First, add the following to {{f|/etc/portage/make.conf}} on the host system :
{{file|name=/etc/portage/make.conf|desc=Portage make.conf file|body=
QEMU_USER_TARGETS="aarch64 arm"
FEATURES="-sandbox -ipc-sandbox -usersandbox candy"
}}

==''Chrooting and Letting the Magic Happen''==

===Entering Franken Chroot===

{{console|body=
###i## mv -v /mnt/piroot/etc/resolv.conf{,.orig}
###i## cp -v -L /etc/resolv.conf /mnt/piroot/etc/
###i## env -i HOME=/root TERM=$TERM /bin/chroot /mnt/piroot /bin/bash -l
###i## export PS1="(Franken_Chroot) $PS1"
}}

===Exiting Franken Chroot and Final Thoughts===

{{console|body=
###i## rm /etc/resolv.conf
###i## mv -v /etc/resolv.conf{.orig,}
###i## exit
###i## umount -v /mnt/piroot/var/tmp/portage
###i## umount -lR /mnt/piroot
###i## sync
