This is actually of some concern, primarily that downloading within PXE (of any type) is quite slow. It's doable, but there are a few PXE stacks that will barf on something that big. Some of those can be "fixed" by chaining first to gPXE then to the install. That said RIP, which I've got in BKO, has an initrd that's about 100M in size, and it works. Just takes forever to load. Case in point: http://boot.kernel.org/bko/pxeknife/linux_boot_disks/rip/tftpboot/rootfs.cgz is an initrd of roughly the size your proposing, and one I know works. Various download times: the above link with wget across the internet to my home: 69s - 1.37 MB/s With tftp from a server in my house to my laptop (with a wifi link involved) 6:15.60 - 262 KB/s Same tftp server only only wired (100mbps) 43.034s - 2.1 MB/s NOTE: this is using the tftp client thusly: time echo "get rootfs.cgz quit" | tftp <server> tftp implementations in PXE stacks are quite a bit slower than this. > (2) The kernel may freak out about storing such a large image in memory so > early on.

It would effectively kill off anything with less than 256M of ram from doing an install. I wouldn't think this is common anymore, but I know machines with 512M of ram are still in production today, and running Fedora. > (4) Doing a large number of PXE-based installs all at once could perhaps bring > a network to its knees.

Doubtful ;-) Just some thoughts, I'm not sure if this kind of change would ultimately be good or bad. The biggest problem I can see if the want for an ever increasing initrd. - John 'Warthog9' Hawley _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
