[OSR-devel] sysfs

[Gordan B. <go...@bo...>]

Quick question, embarrasing as it may be - where does /sys mount point 
get created in the initrd? I have just rebuilt my initrd and there is no 
/sys mount point in it, so mounting /sys fails, which is probably why 
udev startup doesn't create the device nodes, and from there on it all 
goes wrong. grepping for sys and mkdir comes up with nothing... What 
have I broken?

Thanks.

Gordan

I think nothing. Yesterday I realised that /sys is not created. Just change 
boot-scripts/etc/boot-lib.sh function initEnv so that it is automatically 
created:
  echo_local_debug "*****************************"
  echo_local -n "Mounting Proc-FS"
  is_mounted /proc
  if [ $? -ne 0 ]; then 
  	[ -d /proc ] || mkdir /proc
    exec_local /bin/mount -t proc proc /proc
    return_code
  else
    passed  
  fi

  echo_local -n "Mounting Sys-FS"
  is_mounted /sys
  if [ $? -ne 0 ]; then
  	[ -d /sys ] || mkdir /sys 
    exec_local /bin/mount -t sysfs none /sys
    return_code
  else
    passed
  fi

But don't ask me how that missing /sys was missed.

Sorry about that cheers
Marc.

I think there was a dir sys in /opt/atix/comoonics-bootimage/boot-scripts/sys. 
That is dir copied into the initrd and mapped to /.
