Re: [Ltib] Can LTIB compile just one single module without recompiling whole kernel???

[Stuart Hughes]

Hi Quentin,

No, I would not recommend moving stuff out of the kernel and into a
separate package.  If it's already in the kernel leave it there.

A re-build of the un-packed kernel source should be quick, a minute or
so once you've built it once.

Regards, Stuart
