hrm.. does split /usr still work when booting? I'd like to construct an iso image with a small boot archive and then mount a larger /usr off the ISO image (vs. having one larger boot_archive), but don't know if that's something that'd still work

jbk thats how OI is working (from install media) and smartos too. the catch is about getting /usr to be mounted - you have to have the needed bits in rootfs.

jbk: what tsoome said and you need the right scripts from slim_source in the exact right boot order disabling normal mounting or setup scripts.

jbk: might have more luck with a linux-y root pivot

as far as future proofing and such

the problem is because we still boot like it's 2005, making the boot archive too large causes problems

already have hit this with some AMD systems where their UEFI implementations don't leave enough contiguous memory free below 4G

so we can't boot because our boot archives are too large

jbk: need this with another distro than Openindiana when there is no disk to keep / ? All other archives have been 200MB max

it's not for openindiana

but the general AMD issue is true across every illumos distro i've tried

is there enough memory _somewhere_?

yeah... above 4GB

plenty there

and loader etc can't bounce and pull that off

eugh

no, tsoome has been working on it

loader itself can, thats no problem;)

but it's basically unsupported by multiboot

but also apparently dboot seems to have some deep implicit assumptions about how physical memory is laid out

the assumptions about memory layout are on the way - assuming I understand the problem correctly.

booting is hard, and we should stop

that too:) well, the boot as such is not the problem. the problem is keeping some sanity while doing so;)
