# Updating iPXE image
# Updating iPXE images
The netboot image can be updated by building the [AUR
package](https://aur.archlinux.org/packages/ipxe-netboot/) (note that it builds
from git master) and copying the resulting ipxe.pxe, ipxe.lkrn and ipxe.efi to
sitestatic/netboot. Then as Arch Linux Developer sign them with your PGP key
```gpg --output ipxe.efi.sig --detach-sig ipxe.efi```.
The binaries required for iPXE based netboot are updated by copying them from
the [ipxe](https://archlinux.org/packages/community/x86_64/ipxe/) package to
[the static content directory](/sitestatic/netboot/) (with the `run_ipxe`
script the binaries may be tested beforehand):
Testing a build iPXE image requires the 'qemu' package and running the
following command:
```
cp -v /usr/share/ipxe/x86_64/ipxe-arch.efi /usr/share/ipxe/ipxe-arch.{ipxe,lkrn} sitestatic/releng
```
qemu-system-x86_64 -kernel ipxe.lkrn -m 2G

[WKD](https://wiki.archlinux.org/title/GnuPG#Web_Key_Directory) enabled

created for each file:
```
gpg --sender "User Name <your@mail.address>" --detach-sign sitestatic/netboot/*.{efi,ipxe,lkrn}
```
