Slackware 13.0 x86_64 is released as stable!  Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits.  The ISOs are off to the replicator.  This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com.  Please consider
picking up a copy to help support the project.  Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy!  -P.

Subject: [PATCH] modprobe: remove pointless /sys requirement
When modprobe was converted from parsing /proc to parsing /sys, it was not
a straight conversion. Instead, a "sanity" check was added early on where
modprobe would simply abort doing anything useful if /sys isn't mounted.
Unfortunately, this makes modprobe fairly unusable. Considering the
kernel itself can invoke modprobe before userspace gets a chance to start
the init process (and actually mount /sys), we end up with a chicken and
egg issue. Which gets even worse when the kernel keeps running modprobe
over and over and the boot output fills up with:
modprobe: FATAL: /sys is not mounted.
modprobe: FATAL: /sys is not mounted.
modprobe: FATAL: /sys is not mounted.
modprobe: FATAL: /sys is not mounted.
modprobe: FATAL: /sys is not mounted.
modprobe: FATAL: /sys is not mounted.
Since modprobe itself is already written to handle the case where it
cannot figure out whether a given module is loaded (and so was able to run
perfectly fine without /proc being mounted), the check is wholly useless.
