Description Flags
Patch allowing initrds to work with devfs kernels none

Description Nils Philippsen 2001-08-15 20:01:41 UTC 
Initial ramdisks produced with recent mkinitrds will not boot devfs
enabled kernels properly.

The latest version I tried this on is 3.1.6-1.

Steps to Reproduce:
1. Compile kernel with devfs enabled
2. mkinitrd
3. reboot

I'll attach a patch containing two changes:

- nash/mkrootdev() now renames /dev/root (which is already there in
  devfs) prior to making the root device. Perhaps not mkrootdev()ing
  at all is a better way.
- mkinitrd now accepts the --devfs switch which will mount the devfs to
  /dev after pivot_root()ing.

Comment 2 Nils Philippsen 2001-08-15 20:04:50 UTC 
Umm forgot something:

Of course, nash/mkrootdev only renames /dev/root if /dev is a devfs (checks
for existence of /dev/.devfsd).

Could you grab the latest mkinitrd out of CVS and update your patches. Email me
the final patches and I'll integrate them asap. I've marked a couple of bugs
duplicates of this one; they have patches that may or may not help.

I guess you don't want to fix this... As devfs has race conditions, etc
according to everyone I've talked to I'm not going to worry.
