Where I have seen it is on some carrier grade blade systems. Each blade = has a=20 small local boot partition, which a shared (read-only) /usr partition. T= he=20 small boot partition handles initial booting, setup and mounting.. while = the=20 shared partition handles the majority of "unix infrastructure". These systems do not use ramdisks, initrds, etc... I'm also aware of some other systems that do this for boot performance re= asons..=20 they do it for booting quickly to the main UI app, and in parallel mounti= ng and=20 loading additional runtime apps from the /usr disk (RO) and a /var (RW) d= isk.=20 As things are available the UI options are made available to the end user= . The=20 result is a -faster- perceived boot. Again ramdisks/initrds are not used= =20 because of various reasons. --Mark > Philip > > _______________________________________________ > Openembedded-core mailing list > Openembedded-core@lists.openembedded.org > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
