ACL on Ext2/3

  • mit Option acl mounten: mount -o remount,acl /
  • für dauerhafte Nutzung: sed 's/\(ext3\s\+\)/\1acl,/' /etc/fstab | diff /etc/fstab - und das patchen :).
  • apt-get install acl
  • getfacl und setfacl benutzen
    • setfacl -m u:huffna:r file gibt Benutzer huffna Leserechte
    • Achtung: Im Gegensatz zu AFS unterstützt Ext3-ACL auch für einzelne Dateien ACLs.

Aufsetzen von Evolver13 (Ubuntu 7.10 Beta i386)

Allgemeine Dienste

  • ldap über auth-client => ganz isi
  • autofs mit autofs config von evolver12

Windriver (9.01) für Darkwing

  • in redist/linux_wrappers.c: pci_register_driver() statt pci_module_init()
  • Packages: linux-headers-generic linux-source für "make prepare" Informationen bzw. modpost (=> postprocess module symbol versions :))
  • in redist/configure aufrufen (nicht von unten make => versemmelt config)
  • in redist/ make install => fertig
  • chgrp F9_remote /dev/windrvr6; chmod 664 /dev/windrvr6
  • in /etc/udev/rules.d/40-permissions.rules anhängen:
 # Windriver is very old... wrong register
 ACTION=="add", DEVPATH=="/bus/pci/drivers/windrvr6_pci", RUN+="/lib/mk_windrvr6.sh"
 ACTION=="remove", DEVPATH=="/bus/pci/drivers/windrvr6_pci", RUN+="/lib/mk_windrvr6.sh"
  • dazu /lib/mk_windrvr6.sh:
 #! /bin/bash
 
 if [ "$ACTION" == "add" ]; then
   major=`grep -w windrvr6 /proc/devices | cut -f1 -d" "`
   mknod /dev/windrvr6 c $major 0 
   chgrp 1009 /dev/windrvr6
   chmod 664 /dev/windrvr6
 fi
 
 if [ "$ACTION" == "remove" ]; then
   rm /dev/windrvr6
 fi

Hardware

  • EPROM falsches Image
  • ein Jumper falsche Position => falscher Nathanslot aktiviert
  • config_darkwing darkwing.bit 40 (oder darkwing_sctrl3.bit?)
  • config_nathan nathan_top_spikey_ext_clk2_fastsdram.bit 2
  • config_darkwing darkwing.bit 60 (oder darkwing_sctrl3.bit?)
  • dinit -r

Computerzeug, das auch noch erledigt werden will

  • NÜX
