>Release: FreeBSD 2.2.6-STABLE i386
>Environment:
I use a kernel w/o cd9660 fs built in and it doesn't get
loaded on system startup - the first mount of a CD-ROM will have to
load it. The kernel is pretty much GENERIC with unnecessary stuff
removed.
>Description:
When the cd9660 LKM is not loaded and it is not compiled into
the kernel sysinstall can't mount the CD-ROM.
>How-To-Repeat:
Make a kernel w/o cd9660 fs and make sure the cd9660 fs module
is not loaded. Now start sysinstall and try to install some package
from CD-ROM.
>Fix:
This fix I made for 2.2-stable from about a week ago - about
May 17. I copied the code mount_cd9660 uses and added it to the
relevant place in sysinstall. As I was at it I also changed mount() a
little bit to be more the way mount_cd9660 is instead of the - accor-
ding to the comment below the example in vfsload(3) - old way of doing
it.
