2024 is finally the year of linux gaming attempts to play halo and my entire install immediately breaks so bad even the recovery mode can’t use a keyboard
all i did was a pacman -Syu and the piece of shit terrible disaster garbage fire OS flew apart on the next reboot
filesystems failed to mount, so i'm assuming your /etc/fstab got corrupted
i think Arch has a script for regenerating it called genfstab, can't remember the syntax but the archwiki should have it somewhere, which can regenerate it; mount the offending volumes in the recovery shell and run that and it may or may not work
alternatively your disk might've broken but since this is right after an update i think it's just a corrupted fstab or other filesystem failure like missing drivers and not a hardware fault
also i would suggest Void instead of Arch for stability since this thing doesn't break on updates like, ever, but also Void is a weirdass distro in other ways so maybe not the best choice unless you're a weirdo like me
