/dev on tmpfs and MAKEDEV overwritten by ./build.sh

[Philip Dodd <philip.dodd%free.fr@localhost>]

Hi,

I have an issue with my box when I update from source with ./build.sh. 

Context :

- I read some horror stories about /dev on a WAPBL slice
- I learned that if the kernel couldn't find /dev/console, it'd run MAKEDEV

Those two put together, plus the fact that I like the idea that 
non-permanent stuff can sit on tmpfs made me remove the entries on my 
/dev slice, except MAKEDEV, and let the script recreate everything at 
boot, which takes next to no time.

However, I updated my system from sources, and after the reboot after a 
'./build.sh -O ../obj -T ../tools -U  install=/' it dumped on boot, 
unable to find /dev/console.  After getting access to the box it seems 
indeed that MAKEDEV is no longer in /dev on the / slice, and therefore 
cannot be found. 

I'm guessing that the union mounted /dev overwrote the MAKEDEV on the / 
disk slice when ./build.sh did its install and so that after the tmpfs 
/dev was no longer mounted with union, there was nothing on the 
partition.  I booted from the install CD, copied back the MAKEDEV and 
rebooted, and all was fine.

Is there a better way to manage this, or do I just have to note that 
after the install=/ I have to somehow get a copy of MAKEDEV back in /dev 
on the / slice (which will be union'ed with the tmpfs fs).

Thanks for any help,

Phil
