[Pkg-uml-pkgs] Bug#518774: asterisk hangs when started under User-mode Linux

[Ivan Shmakov]

Package: user-mode-linux
Version: 2.6.26-1um-2

	When started under user-mode-linux, asterisk (as of
	1:1.4.21.2~dfsg-3) hangs, with the last lines of the strace(1)
	output being like the following:

# strace asterisk -p -U asterisk 
...
fstat64(3, {st_mode=S_IFREG|0644, st_size=925, ...}) = 0
mmap2(NULL, 925, PROT_READ, MAP_SHARED, 3, 0) = 0x4001d000
_llseek(3, 925, [925], SEEK_SET)        = 0
munmap(0x4001d000, 925)                 = 0

_llseek(3, 519, [519], SEEK_SET)        = 0
fstat64(3, {st_mode=S_IFREG|0644, st_size=519, ...}) = 0
munmap(0x4001d000, 519)                 = 0
close(3)                                = 0

setuid32(102)                           = 0

	Also, $ ps ax shows:

$ ps ax | grep aste 
 1075 ?        Rsl    0:00 /usr/sbin/asterisk -p -U asterisk
...
$ 

	However, when started without the `-U <user>' option, it seems
	to start just fine, like:

# su -p asterisk -c 'asterisk -d -c -p'
