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
|
||||
```
