For instance, a 2 gig disk image that contains only the necessary data.<BR/><BR/>You should have a script, that on first boot of the freshly-imaged host, will create any partitions or volumes necessary and make filesystems, or just grow the root fs, or whatever. <BR/><BR/>So, Jon, to answer your question. Yes, the system is flexible enough to build whatever you need, but the solution doesn't come from using udp-cast to blast an image, but from the startup and self-configuration decisions the host will make once it has been imaged.Jordan Sisselhttps://www.blogger.com/profile/13694925032675599790noreply@blogger.comtag:blogger.com,1999:blog-3615332969083650973.post-43334212569283737502009-01-16T13:31:00.000-05:002009-01-16T13:31:00.000-05:00I've been using mondorescue for this.

Works better when drive sizes are different etc, assuming your kernel isn't tuned so tight it won't support other hardware.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3615332969083650973.post-32142027646297011392009-01-15T11:12:00.000-05:002009-01-15T11:12:00.000-05:00When using kickstart/FAI etc. it is entirely possi...When using kickstart/FAI etc. it is entirely possible to have nuances in the default state, so it isn't perfect (just the other day I installed two machines at the exact same time and one tripped over a configuration problem that the other didn't have: some aspect of the installation is non-deterministic but I haven't figured out quite which bit yet).<BR/><BR/>However I cannot see doing a raw filesystem-level imaging being remotely feasible, unless you have totally homogeneous hardware. Do you do the imaging at the partition level, or lower? If lower, do you know the parameters for every single hard drive you might have deployed? If at the partition layer, is your system flexible enough to build the partition tables for each different scenario you might face?Jon Dowlandhttps://www.blogger.com/profile/17648099917672954037noreply@blogger.comtag:blogger.com,1999:blog-3615332969083650973.post-20732289929123581222009-01-01T10:25:00.000-05:002009-01-01T10:25:00.000-05:00Debian/Ubuntu have several automatic installatoin ...Debian/Ubuntu have several automatic installatoin packages: FAI (which can be used for other distros/OSen), replicator, systemimager, autoinstall.
