[Buildroot] Fwd: all files and folders seem as an executable file ?

[cem akpolat]

Dear Thomas,

This is the way that I have pack/unpack the .cpio file system:

unpack

sudo cpio -id < ../openwrtWireless

pack

 sudo find . | sudo  cpio --create --format='newc' > /tmp/openwrtWireless

The following shows the folders' permissions, as you see the folders are
seen as executable.


drwxrwxr-x 18 default default   0 May 26 11:10 .
drwxrwxr-x 18 default default   0 May 26 11:10 ..
drwxr-xr-x  2 root    root      0 May 26 11:10 bin
drwxrwxr-x  3 root    root      0 May 26 11:10 boot
drwxr-xr-x  6 root    root      0 May 26 19:15 dev
drwxr-xr-x 20 root    root      0 May 26 19:15 etc
drwxrwxr-x  4 root    root      0 May 26 11:10 home
lrwxrwxrwx  1 root    root      9 May 26 11:10 init -> sbin/init
drwxrwxr-x  5 root    root      0 May 26 11:10 lib
lrwxrwxrwx  1 root    root      3 May 26 11:10 lib32 -> lib
lrwxrwxrwx  1 root    root     11 May 26 11:10 linuxrc -> bin/busybox
drwxrwxr-x  2 root    root      0 May 26 11:10 media
drwxrwxr-x  2 root    root      0 May 26 11:10 mnt
drwxrwxr-x  2 root    root      0 May 26 11:10 opt
dr-xr-xr-x 56 root    root      0 May 26 19:14 proc
drwx------  3 root    root      0 May 26 19:18 root
lrwxrwxrwx  1 root    root      3 May 26 11:10 run -> tmp
drwxr-xr-x  2 root    root      0 May 26 11:10 sbin
dr-xr-xr-x 12 root    root      0 May 26 19:14 sys
drwxrwxrwt  5 root    root    380 May 26 19:15 tmp
drwxrwxr-x  8 root    root      0 May 26 11:10 usr
drwxrwxr-x  5 root    root      0 May 26 11:10 var

best regards,
