"mounting /dev/vg0/root on /sysroot failed" on RPI4

Hi everyone,

I'm trying to install Alpine on an RPI4 with LVM and LUKS. I have already
done it several times without problem but this time I got this error:
"mount: mounting /dev/vg0/root on /sysroot failed: No such file or
directory and the emergency recovery shell is launched. I manage to
continue the boot by manually mounting the partition and it starts as it
should:

```
nlplug-findfs: crypt_load(/dev/mmcblk0)
mount: mounting /dev/vg0/root on /sysroot failed: No such file or directory
Mounting root failed.
initramfs emergency recovery shell launched. Type 'exit' to continue boot
sh: can't access tty; job control turned off
~ #
~ # cryptsetup luksOpen /dev/mmcblk0p1 lvmcrypt
--key-file=/crypto_keyfile.bin
~ # lvm vgchange -ay vg0
3 logical volume(s) in volume group "vg0" now active
~ # mount /dev/vg0/root /sysroot
~ # exit
```

Once the system is started, I check that the modules are loaded, that the
cmdline.txt is ok and I rebuild the initial RAM disk:

```
$ cat /etc/mkinitfs/mkinitfs.conf
features="base mmc usb ext4 mmc vfat nvme vmd lvm cryptsetup cryptkey"
$
$ cat /boot/cmdline.txt
modules=loop,squashfs,sd-mod,usb-storage,vfat,ext4,nvme,vmd,kms,lvm,cryptsetup,cryptkey
quiet console=tty1 rootfstype=ext4 slab_nomerge init_on_alloc=1
init_on_free=1 page_alloc.shuffle=1 pti=on vsyscall=none debugfs=off
oops=panic module.sig_enforce=1 lockdown=confidentiality mce=0 loglevel=0
root=/dev/vg0/root cryptroot=/dev/mmcblk0 cryptkey=yes cryptdm=lvmcrypt
$
$ ls /crypto_keyfile.bin
/crypto_keyfile.bin
$ sudo mkinitfs -c /etc/mkinitfs/mkinitfs.conf -b / 6.6.4-0-rpi
==> initramfs: creating /boot/initramfs-6.6.4-0-rpi
$ sudo reboot
```

But that doesn't change anything and I fall back again into the emergency
shell.
Usually it works well and I can't find the difference in this case.. any
idea?

Thanks in advance for the help.
