Hi,
I have installed Chimaera on my Ultrabook - first as beta, then
upgraded constantly.
The system has a dual-disk setup under windows called smart cache or
fast cache.
One spinning rust and one smaller SSD. ON windows the two drives are
one as one with a cache.
Actually, when installing linux, they are seen as two drives, sda and
sdb. I thought, originally, to install on the SSD disk so to have a
fast boot system and the rest of apps and user directories on spinning
rust. However, I could not even partition the SSD, it always gave
errors. SO I installed everything on sda. I had delays at boot
however, later.
Now, with the latest kernel upgrade the delays became quite unbearable.
First.. can I stop this? maybe disabling or tweaking some setting?
Second, can this SSD disk actually be used? 32gb should be plenty for
kernels boot and core system!
