Re: [PLUG] Creating a large, multiple device read-only file system
|
Are you looking to buy 20 DVD readers and use JBOD or some form of
RAID? That sounds theoretically possible, albeit not a great idea.
It'd be cheaper to get an external drive and use that. Probably faster
too. If you're looking to use a lot of disks in a single drive, and
swap discs out as needed on demand, I don't know of any kind of
filesystem or layer that lets you do that.

Yeah, I'd imagine- things like openwrt work kinda like that (except
they have a separate jffs partition so you can save and restore
important stuff that isn't included in the distribution. Like ooohhhh,
firewall rules for instance...)
I'd invest in a lot of RAM- you'll need it for temp things that need
runtime writing. Some things off the top of my head are /tmp, /var/tmp,
/var/cache, /var/log. Etc
You'll also need to do a good amount of initramfs/initrd hacking unless
you planning on remounting the thing ro late/last in the boot process.
Do a lot of reading on livecd's and other things that use static /'s,
lots of nifty ideas for hacks there.
It might help if we know what it's for also (unless you're prohibited
by NDA)- might get some good alternatives if possible. As we all know
by now, there's usually more than one way to do something in *nix
(lack of GPG due to message sent via blackberry device)
