FAQ

May I use arbitrary package names?

No, package names must reflect the package names in the archive, so that there's a single namespace to remember and respect.

I've tried to use a different Ubuntu version and it failed?

The mapping is manual for now. Let us know and we'll fix it.

Can I use multiple repositories in a Chisel release?

Not at the moment, but maybe eventually.

Can I use non-Ubuntu repositories?

Not at the moment, but eventually.

Can multiple slices refer to the same path?

Yes, but see below.

Can multiple slices output the same path?

Yes, as long as either both slices are part of the same package, or the path is not extracted from a package at all (not copied) and the explicit inline definitions match exactly.

Is file ownership preserved?

Not right now, but it will be supported.
