Using initcpio
--------------
This allows you to remount the root file system using 9p. No changes are necessary if you only want to mount a 9p filesystem after booting.
Add the following files:
`/etc/initcpio/hooks/9p_root`
```bash
#!/usr/bin/bash
run_hook() {
mount_handler="mount_9p_root"
}
mount_9p_root() {
msg ":: mounting '$root' on real root (9p)"
if ! mount -t 9p "$root" "$1"; then
echo "You are now being dropped into an emergency shell."
launch_interactive_shell
msg "Trying to continue (this will most likely fail) ..."
fi
}
```
<hr>
`/etc/initcpio/install/9p_root`
```bash
#!/bin/bash
build() {
add_runscript
}
```
Change the following options in `/etc/mkinitcpio.conf`:
```bash
MODULES="virtio_pci 9p 9pnet 9pnet_virtio"
HOOKS="base udev autodetect modconf block filesystems keyboard fsck 9p_root" # appended 9p_root
```
