[SOLVED] Arch boots into emergency mode
When I boot arch using grub, I'm greeted by this message.
I've reinstalled grub, regenerated initramfs, regenerated /etc/fstab, reinstalled linux and yet no luck.

Yes because for some reason I thought fstab was getting removed. What should I do?

Re: [SOLVED] Arch boots into emergency mode
Try just to keep the last 2 entry. Remove other entry and reboot.

removed /etc/fstab and ran genfstab again and it's fixed. Thanks!

For future reference, you might want to look up what >> does in bash.

Re: [SOLVED] Arch boots into emergency mode
Yes because for some reason I thought fstab was getting removed.
there's a difference between a single redirect > and a double redirect >>
the single redirect creates a new file or completely overwrites an existing one
the double redirect appends to an existing file
why the double redirect is used:
/etc/fstab is such an important file that an empty default one is already created during initial pacstrap
calling genfstab with the appending doubke redirect means to append the output of genfstab to the existing empty fstab template
doing so multiple times will append multiple double entries which can end up in a bad fstab like yours
as for why the guide does it this I'm not sure as it's written for a new install with an empty fstab anyway - so a simple overwriting single redirect would do the job just fine
maybe it's just to keep the few template lines atvtge top - maybe there's another more specific reason
tldr: you always want a fstab with each mountpoint only show up once
