Cannot mount root at boot on fresh installation

Hello,

After a fresh installation using archinstall, I cannot mount root filesystem:

performing fsck on '/dev/nvme0n1p5'
mounting /dev/nvme0n1p5 on real root
mount: /new_root: mount(2) system call failed: No such file or directory

My fstab, generated during installation is:

# Static information about the filesystems.
# See fstab(5) for details.

# <file system> <dir> <type> <options> <dump> <pass>
# /dev/nvme0n1p5
UUID=417964d3-bdea-4c82-baae-e61d2ee9f816       /               btrfs           rw,relatime,ssd,space_cache=v2,subvolid=5,subvol=/      0 0

# /dev/nvme0n1p2

while the output of blkid command is the following:

I had an error at boot from dmesg concerning extra spaces in fstab, I removed them and I cannot see that error anymore, but I still can't mount the root at boot.

This is my mkinitcpio.conf:

MODULES=(btrfs)
BINARIES=(btrfs)
FILES=()
HOOKS=(base udev autodetect keyboard keymap modconf block filesystems fsck)

Re: Cannot mount root at boot on fresh installation

I had a similar situation and i fixed it by modifying the boot entry for systemd-boot.  I had to add option root=UUID=417964d3-bdea-4c82-baae-e61d2ee9f816 to the /boot/loader/entries/arch.conf file.  (I used the UUID from your post so you could possibly copy/paste if this is what you need to do smile )

Thanks!

I modified the file from

to

options root=UUID=417964d3-bdea-4c82-baae-e61d2ee9f816 rw intel_pstate=no_hwp rootfstype=btrfs

and now it boots!

Do you think there's a bug on archinstall?
