Re: [gentoo-catalyst] catalyst aborts, can not unmount /dev

[Jacques Landru]

Hi

It seems that problem comes from the catalyst2 cache options. I had the 
same behaviour
untill I unvalidate kerncache pkgcache, seedcache and snapcache options 
in my /etc/catalyst2.
My options field is just
options="autoresume ccache"

LiveCD rebuild is longer, but all busy device unmount problems, I had, 
seem to be solved.

Hope this can help gentoo catalyst2 developper...
