Hi guys, I want to builed a custom liveOS booting from PXE to do some sysadmin operations. I want to create liveos base on centos 6.5 under Centos 6.5 host. I install 'livecd-tools' from EPEL mirror and some 'dracut-*' packages: # rpm -qa|grep livecd livecd-tools-13.4.5-1.el6.x86_64 # rpm -qa|grep dracut dracut-004-336.el6_5.2.noarch dracut-tools-004-336.el6_5.2.noarch dracut-kernel-004-336.el6_5.2.noarch dracut-network-004-336.el6_5.2.noarch dracut-generic-004-336.el6_5.2.noarch This is my ks.cfg paste: http://ix.io/elW I created ISO by: livecd-creator -c centos6.liveos.ks.cfg -f Centos6u5-LiveCD -v -d after creating Centos6u5-LiveCD.iso, I try to boot it from PXE. LABEL centos6u5-liveos KERNEL images/6u5/vmlinuz0 APPEND initrd=images/6u5/initrd0.img root=live: http://10.21.10.2/6u5/squashfs.img biosdevname=0 PXE boot failed with kernel pannic: dracut: FATAL: Don't know how to handle 'root=live:http:// .../squashfs.img' dracut: Refusing to continue I google for this error, get some info about : 'initrd0.img' missing 'livenet' module from this topic: http://bugs.centos.org/view.php?id=6112 so I try to add 'livenet' module to initrd0.img: dracut -v --force -a "livenet" initrd0.img 2.6.32-431.29.2.el6.x86_64 After add 'livenet', I retry to boot it from PXE, but it doesn't work. I get the same kernel pannic error. How could I create a liveOS booting from PXE with 'root=live:http://.../squashfs.img' ? Thanks.

Hi All, On my live USB stick, I installed a couple of large RPM's that I no longer needed. So I removed them (rpm -e xxx). Question: do I get that space back or it is permanently used? Many thanks, -T

Hi All, I am noticing a few ISO's now support "dd" to install on a Live USB. Does anyone know if this method will support "persistence"? Many thanks, -T
