A vueltas con el NAS, no he encontrado la manera de cambiar los puntos de montaje por defecto para los discos duros.
Y la verdad, no me gustaba la idea de tener el 2º disco en “/home/Disk_2”, asi que aprovechando el sistema “funplug”, he decido añadir un script propio para montar en durante el boot el 2º disco donde yo quiero.

El script es el siguiente:
[cc lang=”bash” theme=”blackboard”]
#!/bin/sh
# EXIT CODES:
# 0 OK
# 1 MOUNT FAIL
# 2 UMOUNT FAIL
# 99 undefined error

DISK2=”/home/Disk_2″
DEVICE2=”/dev/sdb1″
MYMOUNT=”/home/Public/mountpoint”
# check if mounted
checkmounted()
{
# returns: 0 umounted, 1 wrong, 2 OK
local MOUNTED=”$(df | grep “^$DEVICE2″)”
if [[ “$MOUNTED” ]]
then
if [[ “$(echo $MOUNTED | grep $MYMOUNT)” ]]
then
return 2
else
return 1
fi
else
return 0
fi
}
# mount
mount_it()
{
mount $DEVICE2 $MYMOUNT
sleep 2
checkmounted
AUX=$?
if [ $AUX -ne 2 ]
then
echo “FAIL mounting”
exit 1
fi
}
# umount
umount_it()
{
umount -lf $DISK2
sleep 2
checkmounted
AUX=$?
if [ $AUX -ne 0 ]
then
echo “FAIL umouting”
exit 2
fi
}
# check again

main()
{
checkmounted
AUX=$?
case $AUX in
0)
mount_it
;;
1)
umount_it
mount_it
exit 0
;;
2)
echo “OK”
exit 0
;;
*)
echo “FAIL STATUS”
exit 99
;;
esac
}
main
[/cc]

Como véis, únicamente compruebo que está montada (variable $DISK2), desmonto y monto en el sitio que yo quiero (variable $MYMOUNT).

Hi folks!
Following with my CH3HNAS adventures, I’ve decided to build my own cross-compiling environment based on the wonderful instructions from Henk-Jan.
To avoid unexpected issues on my Arch distro, I’ve created a new VM running debian.
Here I found the 1st issue, there’s no gcc-4.1 on the last debian version, so I setted up lenny’s repos:
[cc lang=”bash” theme=”blackboard”]
cp /etc/apt/sources.list /etc/apt/sources.list.orig
echo “deb http://ftp.us.debian.org/debian/ lenny main contrib non-free” > /etc/apt/sources.list
echo “deb-src http://ftp.us.debian.org/debian/ lenny main contrib non-free” >> /etc/apt/sources.list
apt-get update
apt-get install gcc-4.1 g++-4.1
mv /etc/apt/sources.list /etc/apt/sources.list.lenny
cp -fv /etc/apt/sources.list.orig /etc/apt/sources.list
[/cc]
Having the minimal debian distro, “bzip2” is necessary too.

I get an estrange error at the 1st step’s while “making” the build environment:
[cc lang=”bash” theme=”blackboard”]
scripts/unifdef.c:209: error: conflicting types for ‘getline’
/usr/include/stdio.h:XXX: note: previous declaration of ‘getline’ was here
[/cc]
I was running crazy with that till I found this simply solution.
The problem is that if you want to use the “Makefile” provided, the kernel source is bzip’ed, so callme fool, but I bunzipped/bziped again with the patch inside :)
[cc lang=”bash” theme=”blackboard”]
cd OXNAS810/src/rootfs/buildroot/../buildroot-archives/
tar xjfv linux-2.6.24.7.tar.bz2
sed -i “s/getline/uc_&/” ./linux-2.6.24.7/scripts/unifdef.c
mv linux-2.6.24.7.tar.bz2 linux-2.6.24.7.tar.bz2.orig
tar cjfv linux-2.6.24.7.tar.bz2 linux-2.6.24.7
[/cc]
And then I simply run:
[cc lang=”bash” theme=”blackboard”]
make
[/cc]
To build the environment.
