[Pkg-uml-pkgs] Bug#396506: user-mode-linux: /dev/shm/ must be not mounted noexec

[Ritesh Raj Sarraf]

Package: user-mode-linux
Version: 2.6.18-1um-1
Severity: normal

UML doesn't start anymore. Following is the message I get:

Checking that ptrace can change system call numbers...OK
Checking syscall emulation patch for ptrace...OK
Checking advanced syscall emulation patch for ptrace...OK
Checking for tmpfs mount on /dev/shm...OK
Checking PROT_EXEC mmap in /dev/shm/...failed: Operation not permitted
/dev/shm/ must be not mounted noexec

/dev/shm/ is tmpfs and is mounted noexec

Please also follow the following thread for the particular patch which
brings this issue:
http://lkml.org/lkml/2006/4/10/255

I think the initscripts should be modified to mount /dev/shm as noexec
or atleast should go into that mode once uml gets installed.
