We need /dev/ptmx -> /dev/pts/ptmx (for devpts -o newinstance) Other way to do this thing is via bind mount (as said kernel doc[devpts.txt]). This should be done in this way at least for /dev as devtmpfs in the chroot. Since we can not touch /dev (devtmpfs), because devtmpfs is "singleton", just use bind method and avoid interference. Do it the same for both modes of /dev (tmpfs) and (devtmpfs) to keep it simple. Currently devpts in chroot is not working without this when using /dev as devtmpfs, this fixes this issue (opening /dev/ptmx, creates devices nodes on outside /dev/pts) Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar> --- mkarchroot.in | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/mkarchroot.in b/mkarchroot.in index d45cfba..1d1c310 100644 --- a/mkarchroot.in +++ b/mkarchroot.in @@ -117,7 +117,7 @@ chroot_mount() { [[ -e "${working_dir}/dev/pts" ]] || mkdir "${working_dir}/dev/pts" mount -t devpts devpts "${working_dir}/dev/pts" -o newinstance,ptmxmode=666 - ln -s pts/ptmx "${working_dir}/dev/ptmx" + mount -o bind "${working_dir}/dev/pts/ptmx" "${working_dir}/dev/ptmx" [[ -e $cache_dir ]] || mkdir -p "${cache_dir}" [[ -e "${working_dir}/${cache_dir}" ]] || mkdir -p "${working_dir}/${cache_dir}" @@ -148,6 +148,7 @@ copy_hostconf () { chroot_umount () { umount "${working_dir}/proc" umount "${working_dir}/sys" + umount "${working_dir}/dev/ptmx" umount "${working_dir}/dev/pts" umount "${working_dir}/dev/shm" umount "${working_dir}/dev" -- 1.7.9.2
