For linux... just type 'set' in the terminal and you'll see all the environment variables which are configured within Linux automation. Here's a few of the Altiris related ones which are set, as taken from my test setup...
ALTIRIS_BDC=BDC6.9.9172.371
ALTIRIS_BOOTDEVICE=PXE
ALTIRIS_BOOTDISK=

ALTIRIS_DS_SERVER=ALTIRIS-DS

ALTIRIS_PREBOOT=LINUX
ALTIRIS_PREBOOT_ID=LINUX_X86
ALTIRIS_PREBOOT_NAME=LinuxPE
ALTIRIS_PREBOOT_NAME2=LinuxPE
ALTIRIS_PREBOOT_SUBSUBTYPE=LINUX
ALTIRIS_PREBOOT_SUBTYPE=LINUX
ALTIRIS_PREBOOT_UID=LINUX_X86
ALTIRIS_PROCESSOR=x86

ALTIRIS_PXE_INTERFACE=eth0
ALTIRIS_PXE_IP=192.168.157.100

ALTIRIS_SHARE=/mnt/ds
ALTIRIS_UNC=//ALTIRIS-DS/eXpress
ALTIRIS_VER=DS6.9
In the main, not very exciting....
For the site server thing -yes I should get my finger out and document this. Was held up by a slight loss of work from a harddisk failure and I feel a certain anguish having to re-write some of my unpublished work from scratch. Losing data is painful, not to mention really, really stupid.
Moving on from my data berevement, I'll have this site server image share piece within PXE posted within the next couple of days ;-)
Kind Regards,
Ian./
