I'm currently updating the transfer module to reflect the design specified in the DC documention. I'd like to make sure it fits the needs of others too so here's the general idea of what I'm doing.
The Transfer module lays out the bits onto the disk. There will be 2 ways of doing so, using cpio and IPS. There will be 2 possible cpio transfer methods, one will cpio the entire contnets of the src directory to the destination directory, the other will cpio files listed in a specified file to the destination directory. Currently there exists the code to cpio an entire directory. This code is being looked at to make it independent of live CD functionality. It should just cpio the files from one directory to another, and deal with the issue of zero length files. The directory to cpio from will be provided in TM_CPIO_SRC_MNTPT and the mountpoint to cpio the files to will be specified in the attribute TM_CPIO_DST_MNTPT. The new function to cpio a filelist of files will accept a file which will list all of the files to be cpio'd to the designated mountpoint. This will be specified in the attribute TM_CPIO_LIST_FILE. The user will be allowed to specify a source mountpoint that all the files in the filelist will be referenced from. This is optional and will be specified in TM_CPIO_SRC_MNTPT. The destination the files will be cpio'd to will be specified in TM_CPIO_DST_MNTPT and is manditory. Zerolength files will not be detected or corrected. A new function to perform IPS initialization will need to be created. It will perform the equivalent of the following: pkg image-create -F -a opensolaris.org=TM_IPS_PKG_SERVER TM_IPS_MNTPT. A new function to perform IPS verification will need to be created. It will need to verify that the packages listed in TM_IPS_PKGS are contained in the repository located at TM_IPS_PKG_SERVER. A new function to perform IPS retrieval will need to be created. The function will retrieve the packages listed in TM_IPS_PKGS.
