Hi,
I have been tracking down a python3 bug and it turns out to be caused by our chroot building. Essentially the permissions of /dev/shm are different in the chroot than on the system:
allan@mugen /home/arch/chroot/stable-i686/copy/dev
ls -ld shm drwxr-xr-x 2 root root 40 Jul 12 15:16 shm
allan@mugen /dev
ls -ld shm drwxrwxrwt 2 root root 40 Aug 14 10:23 shm
So when configure scripts try to test for POSIX semaphores by writing in that directory, they fail.
Looking at the relevant line in mkarchroot: mount -o bind /dev "${working_dir}/dev"
Doing that manually show the same issue. Should we add
chmod 1777 "${working_dir}/dev/shm"
after the mount? It fixes my issue but feels hackish. Any other suggestions?

Did you try this patch: http://projects.archlinux.org/devtools.git/commit/?id=f7b67c25ff4a3f1f290c29...
Umm.. has anyone? I am fairly certain that the mount command is wrong. + [ -e "${working_dir}/dev/shm" ] || mkdir "${working_dir}/dev/shm" + mount -t tmpfs shm /dev/shm "${working_dir}/dev/shm" Should be: mount -t tmpfs shm "${working_dir}/dev/shm" + [ -e "${working_dir}/dev/pts" ] || mkdir "${working_dir}/dev/pts" + mount -t devpts devpts /dev/pts "${working_dir}/dev/pts" Delete /dev/pts here too.
