What do you want to use it for.
basically we have a system that is booting from a ramdisk and is limited by memory. by doing this we have the ability to only allocate the amount of space that is used by the files. This is then overlayed on a ramfs (ala tmpfs) that can grow if necessary. in short it just minimises the amount of memory that needs to be used. >> - better support for running without swap >> o hence having a non-swap backed ramfs > > Huh ? Solaris works just perfectly without swap and has done so for > many years. okay, i was not aware of that (hence the disclaimer about naivety to begin with ;-) if you have a pointer about how to configure this I'd appreciate it.

So what am I missing about your request ? Okay, that's good. Do you have the support for x86 too? I was thinking more about support on top of Xen. With Xen you are able to migrate sessions across computers and with hotplug cpus you can migrate to different number of cpus. I'd like to be able migrate a session of my server to my laptop whilst i do some hardware tinkering, then migrate it back. No interruption to service everythings fine. >> - better driver/device support for x86 (there is a lot of info >> missing from prtconf that would be available in other OS's >> through /proc, /sys or sysctl) > > What about prtdiag(1m) and smbios(1m). as far as i can tell prtdiag is not available on x86. I haven't had a look at smbios. I can get information through dmidecode too, but that is static information that is passed from the bios (in the same way as i can dump the acpi tables). ndd seems to have some of this information too, but it's pretty confusing. probably most of these concerns are because i haven't been living with solaris for long enough.. peter _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
