[uml-devel] NPTL can't be disabled in fc4?

[William Stearns <wstearns@pobox.com>]

Good afternoon, all,
 	I tried to boot an fc4 VM ( http://www.stearns.org/uml-root/ )on 
zaphod.
 	I compiled 2.6.12-mm1-um26121_20050627 at Jeff's suggestion, and 
still get:

Setting hostname placeholder.stearns.org:  [  OK  ]
set_thread_area failed when setting up thread-local storage

 	It doesn't appear that any of the patches in Jeff's current 2.6 
quilt patch set refer to set_thread_area (Although I could believe that 
one of them addresses it indirectly so the string doesn't show up in the 
patches.)
 	Even adding LD_ASSUME_KERNEL=2.4.1 to the end of the kernel 
command line (which, according to doc/kernel-parameters.txt passes that 
environment variable on to the environment inside the VM) doesn't help. 
LD_ASSUME_KERNEL=2.2.5 on the kernel command line also exhibits 
set_thread_area failed....
 	I've also tried disabling nptl from userspace with the following 
added lines:

/etc/profile.d/glibc.sh
export LD_ASSUME_KERNEL=2.4.19

/etc/init.d/functions
export LD_ASSUME_KERNEL=2.4.19

/etc/initscript : (make mode 755)
export LD_ASSUME_KERNEL=2.4.19
eval exec "$4"

 	Still hitting that set_thread_area error.

 	Is there _any_ way to convince an fc4 userspace to not use NPTL?
 	Cheers,
 	- Bill
