Re: [coLinux-devel] The big TODO list

[Digital I. Inc. <ok...@di...>]

Hello Chris.

This is same issue as you discussed in the previous thread.
and I am for your opinion - using "device alias" would be the right answer.
I dont know which is better, device name approach( your opinion) or
major/minor approach(Daniel Slater's opinion),
anyway, aliasing by kernel layer would be better.
It can be applied for all file systems without fsck problem.

one proposal -
there are many virtualizing technology. UML, coLinux, Xen, Plex86, LilyVM, ,,,.
and they adopt almost same way for using a distribution.
maybe the biggest difference is a device name.

I ask you that it is impossible to unite all formats?
in other words, I hope "Install Once, Runs Anywhere!."
