Hi,
i'm triing to free some RAM memory from my WL500Gp with KAMIKAZE 7.09.
I know that /tmp filesystem use 50% of RAM memory. I've changes a /etc/preinit:
#!/bin/sh
# Copyright (C) 2006 OpenWrt.org
export PATH=/bin:/sbin:/usr/bin:/usr/sbin
. /etc/diag.sh
failsafe_ip() {
ifconfig $ifname 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255 up
}
failsafe() {
[ -n "$ifname" ] && grep "$ifname" /proc/net/dev >/dev/null && {
failsafe_ip
netmsg 192.168.1.255 "Entering Failsafe!"
telnetd -l /bin/login <> /dev/null 2>&1
}
lock /tmp/.failsafe
ash --login
}
mount none /proc -t proc
mount none /sys -t sysfs
size=$(awk '/MemTotal:/ {l=5242880;mt=($2*1024);print((s=mt/2)<l)?mt-l:s}' /proc/meminfo)
#mount none /tmp -t tmpfs -o size=$size,nosuid,nodev,mode=1777
#mount none /tmp -t tmpfs -o size=5242880,nosuid,nodev,mode=1777
mount none /tmp -t tmpfs -o size=2621440,nosuid,nodev,mode=1777
......I've restart the router but i see that thare aren't changes.

/dev/scsi/host0/bus0/target0/lun0/part1 3.6G 8.5M 3.6G 0% /mnt/disc0_1...in sense that the /tmp filesystem is now 2.4 Mb, but free memory is fixed.
Can someone explain to me about this?
Is the kernel the problem?
