Yeah, maybe i was counting kernel+initrd. Notice though that yaboot+netboot has a limited buffer of 6MB, which we can't change without a 6 month flamewar with Ethan Benson, well, maybe this could be made better now that he fears people just taking over yaboot maintenance from him ... Still, d-i right now creates a 8MB prep partition by default, which may be limit for this. > > > The upside is that the initramfs created should be more or less > > > identical for every system and is resilient against people moving the > > > drive from one machine to the other, doing perfect copies (using ghost, > > > dd, or whatnot), or using an already generated initramfs to recover > > > broken systems on other machines. > > > > > > I'd argue for keeping that mode as default if possible because there > > > isn't any benefit to the smaller initramfs in 95% of cases, and it > > > increases the risk of a non-booting system. > > > > I wonder about one thing though, since this is basically a ramdisk, once the > > boot is over, what happens to the memory used to hold it ? > It gets freed as part of run-init, which goes through and rm's > everything on the ramdisk to cause it to be returned to the system.
