Strange behaviour of inittab

I'm on drugs, sorry if this post is illegible.

The original inittab included by BuildRoot looked like this:

# Startup the system
::sysinit:/bin/mount -o remount,rw /
::sysinit:/bin/mount -t proc proc /proc
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mount -a

Anyone else have a problem with this? On my mips, I have an NFS mounted RFS. With the above configuration, I cannot get the system to remount because proc is not mounted (apparently this version of BusyBox mount requires proc????).

The fix I have done is to reverse the mounting/remounting of proc and the RFS as follows:

# Startup the system
::sysinit:/bin/mount -t proc proc /proc
::sysinit:/bin/mount -o remount,rw /
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mount -a

The question I have is should we change the inittab from within BuildRoot or is there really only a problem with something in my configuration?

All the busybox versions I've used required /proc to be mounted. In particular /proc/filesystem which is parsed by busybox to guess the available filesystems supported by the kernel when mounting with "-t auto".

inittab ordering causes mount to fail on remount,rw. inittab changed to mount /proc first.

Committed, thanks - Sorry for the slow response.
