pm segfaults if LD_LIBRARY_PATH is missing like on login with ssh
$ su -c "/system/bin/pm"
[1]   Segmentation fault      pm
$ su -c "LD_LIBRARY_PATH=/vendor/lib:/system/lib pm"


if pm is not found like this
$ /system/bin/pm list packages
sh: /system/bin/pm: not found
you can do
/system/bin/sh -c "/system/bin/pm list packages"
or prepend /system/bin/pm with
#!/system/bin/sh

hostap with a wifi usb stick on demand 
Friday, November 9, 2012, 09:37 - System, Network, Debian/Ubuntu

After plug in of a wifi usb stick linux act's as a hostap.

apt-get install isc-dhcp-server hostapd

changes in /etc/hostapd/hostapd.conf
interface=wlan0
driver=nl80211
ssid=MYSSID
country_code=AT
ieee80211d=1
hw_mode=g
channel=11
beacon_int=1000
dtim_period=20
ieee80211n=1
wpa=2
wpa_passphrase=MYPASSPHRASE
wpa_pairwise=TKIP CCMP

/etc/network/interfaces
iface wlan0 inet static
  address 192.168.9.1
  netmask 255.255.255.0
  hostapd /etc/hostapd/hostapd.conf
  up iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
  up /etc/init.d/isc-dhcp-server restart
  down iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
  down killall hostapd

first check vendor and product id with lsusb:

/etc/udev/rules.d/local.rules
ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="148f", ATTRS{idProduct}=="3070", \
                                                     RUN+="/sbin/ifup wlan0"
ACTION=="remove", SUBSYSTEM=="net", KERNEL=="wlan0", RUN+="/sbin/ifdown wlan0"

On booting this does not work for me so i started the hostap by

/etc/rc.local
lsusb | grep -q "148f:3070" && /sbin/ifup wlan0
