BTW they also provide Glibc-2.0.7, Glibc-2.2.5 libraries that can be used
for compatibility.

It would be a great idea to have Asterisk boot from Compact Flash.  You
could easily fit everything on 32MB flash card, and then you could add
capacity for voicemail. 

Any idea on how much space one would need for voicemail with wav support?  A
512 MB CF card is 85$ US at Sandisk.com.  You can buy an IDE to CF adapter
for around 15$US.  

When Bering boots it loads everything into a RAM based filesystem.  Anyone
see any drawbacks in running an * system using a RAM based file system and
booting from CF?  If you needed additional capacity for VM you could add an
IDE drive.  The benefits to not using an IDE drive would mean one less
mechanical device prone to failure.
