[Pkg-xen-devel] About libc/tls

[Ralph Passgang]

sorry, that was a stupid question. why should a file in /etc disappear just 
because of a reboot.

hmmm. so touching that file is more or less the same as moving the /lib/tls 
directory. It's more elegant, because moving the directory is not a solution 
for the case that libc6 is updated. on the other hand touching 
the /etc/ld.so.hwnocap file would be a solution for the libc6 upgrading 
problem.

if we go this way, we should try to create the /etc/ld.so.hwnocap file as soon 
as possible after the init process to not have services started in an 
tls-enabled mode. We should also remove this file again in a very early 
runnlevel if a non-xen kernel is running (again).

Is that also a solution for the initrd/tls-problem? A initrd that has been 
created on a tls-enabled system will cause xen to warn about tls. What about 
the /etc/ld.so.hwnocap file in combination with the initrd-creation? Will a 
initrd image warn about tls at boot time or not?
