On my main machine, I'm currently using [Asahi Linux](asahilinux.org/) (on a macbook m1). I've recently broken my system, which wasn't able to boot because of a broken `/etc/fstab`.
|
|
|
|
On my previous setups, I was able to easily plug an usb key and boot to it to solve my issues, but here I wasn't sure how to deal with it.
|
|
|
|
After playing a bit (without much luck) with [qemu and vagrant](https://github.com/leifliddy/fedora-macos-asahi-qemu/), someone pointed me to the right direction: using alpine linux.
|
|
|
|
Here's what I did to solve my broken install:
|
|
|
|
First, install this alpine linux on a key.
|
|
|
|
[Download the iso image here](https://dev.alpinelinux.org/~mps/m1/m1-usb-alpine-install.img.xz), and copy it to a key. I'm not sure why, but `dd` didn't work for me, and I ended up using another tool to create the usb from the iso.
|
|
|
|
```bash
|
|
# When booting, press a key to enter u-boot. Then:
|
|
env set boot_efi_bootmgr
|
|
run bootcmd_usb0
|
|
```
|
|
|
|
Which should get you a session. When connected, do the following:
|
|
|
|
```bash
|
|
# to find the parition you want to mount, marked EFI something
|
|
lsblk -f
|
|
mount label="EFI - FEDOR" /mnt
|
|
|
|
# Install the wifi firmware
|
|
cd /lib/firmware
|
|
tar xvf /mnt/vendor/firmware.tar
|
|
/root/update-vendor-firmware
|
|
rm /etc/modprobe.d/blacklist-brcmfmac.conf
|
|
modprobe brcmfmac
|
|
|
|
# Connect to the wifi
|
|
/etc/init.d/iwd start
|
|
iwctl
|
|
|
|
```
|
|
|
|
In my case, I wanted to mount a btrfs filesystem to fix something inside.
|
|
|
|
```bash
|
|
apk add btrfs-progs
|
|
echo btrfs >> /etc/modules
|
|
modprobe btrfs
|
|
mount LABEL="fedora" /opt/fedora
|
|
```
|
|
|
|
I then could access the filesystem, and made a fix to it.
