Now that DEVTMPFS is enabled by default in the Arch configuration, what are its benefits? Can I make an initramfs without udev now? And if I do will I be able to use root=/dev/disk/by-uuid/xx-yy-zz-etc or any of the similar kernel command line options? -- damjan

Some of the initial setup at boot is simplified. Some race conditions don't exist anymore. And it may happen that future udev features require devtmpfs.
Can I make an initramfs without udev now?
In many cases, yes, but that was also possible before devtmpfs. I'd recommend against it, as you need to configure all necessary modules manually - if their names change during update, your system breaks.
And if I do will I be able to use root=/dev/disk/by-uuid/xx-yy-zz-etc
No.
or any of the similar kernel command line options?
Which ones?

I meant the options like root=/dev/disk/by-label or maybe root=LABEL=Arch or something
No, none of this will work.
As far as im aware it doesnt work with initramfs either.

you can use findfs: dev="$(findfs UUID=<uuid>)" if [ -e "$dev" ] then mount "$dev" /mnt done Regards, Andrej

You are top posting so it's entirelly not clear what are you saying doesn't work. But root=/dev/disk/by-uuid/xx-yy-zz-etc does work with Arch's initramfs with udev.
