[asterisk-biz] Flash IDE

[Luciano Vaccarella]

I was inspired by astlinux, then I bult my one with Gentoo (I don't  
like to use uclib)

I don't like to use ram disk because is a way to waste memory, I  
prefer to create tmpfs where mount relative rw directory,
(the rc and init.d scripts of astlinux can be very useful to  
understand how to do it), this is a map of a generic mount:

/dev/hda1 on / type ext2 (ro,nogrpid)
none on /proc type proc (rw)
none on /dev type tmpfs (rw)
none on /var type tmpfs (rw)
none on /tmp type tmpfs (rw)
none on /dev/pts type devpts (rw)
none on /sys type sysfs (rw)
/dev/hda2 on /mnt/opt type ext2 (rw,nogrpid)
192.168.10.80:/mnt/backup01/vm on /mnt/vm type nfs  
(rw,v3,rsize=32768,wsize=32768,hard,lock,proto=udp,addr=192.168.10.80)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sda2 on /mnt/cf type ext2 (rw,nogrpid)

as you see the hda1 is the system and is ro only, the back up are  
made on a nfs mount

this is the total memoy used by a pbx with 60 user registered

                         total        used            free      
shared    buffers     cached
Mem:        512364      49584     462780          0            
1788      28676
-/+ buffers/cache:      19120     493244
Swap:            0          0          0

and these are the active process

The only problem problem using this method is that make upgrade is a  
bit complicated, the ram disk is more easy because you have just to  
replace the disk image.

For now all of the customer upgrade are made replacing on the site  
the cf disk.
