Hm interesting. Long time ago™ /proc, /sys, /dev etc were all necessary because they weren't necessarily created during initrd phase automatically, but AFAICS at least since ~2006 those are all created at least in initramfs-tools based initramfs automatically during bootup, and for sure dracut (which showed up only after i-t) also will handle those automatically.
But, chroot
-ing to such a system without having /proc, /sys + /dev available for mount --bind
, mount -t proc none /proc
could be annoying?
Interesting. I was thinking, for chrooting you'll need scripting to some tool anyhow.
Actually, I might have been wrong about dracut or it's a dracut bug. Let's see what they reply.
So while my argument might be be correct, it might also currently break dracut based live ISOs.
I am not so sure about this now anymore. Is there a standard or convention how other/most distributions / images handle this?
I'm not aware of systems that don't provide /proc, /sys + /dev on their filesystem, might be done for some images where you don't directly chroot into and don't care about it therefore. But IMO tools failing because /proc, /sys + /dev as directories exist as such (instead of actually checking for their mount points or content) is wrong, so I'd tend to not change anything in grml-debootstrap.
Image should not contain folders /run /sys /proc /dev. These should be deleted at the end of the build process.
Rationale:
https://github.com/dracutdevs/dracut/blob/master/modules.d/90dmsquash-live/dmsquash-live-root.sh
(Some dracut internals: Folder
/run/initramfs/squashfs/proc
is inside theLiveOS/squashfs.img
, which can be based on grml-debootstrap (and created by mksquashfs). An image containing an already existing/proc
folder can be useful for I don't know what. But either the/proc
folder should be complete. This is probably for a complex use case we don't know about. Absent of this, best if the/proc
folder doesn't exist. There should not be an empty folder/proc
inside the image.)Would a PR deleting these folders be welcome?
