| |
Hi,
when trying to create a directory path with 'mkdir -p' with the root being a mount point of a writeable filesystem that exists inside a read-only file system, mkdir return -EROFS.
This was tested with the latest git-tree from: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6
The last kernel I know of this has been working was 2.6.22.
E.g.: |root@triton1:/# mount |rootfs on / type rootfs (rw) |/dev/root on / type jffs2 (ro) |proc on /proc type proc (rw) |sysfs on /sys type sysfs (rw) |/dev/root on /dev/.static/dev type jffs2 (ro) |tmpfs on /dev type tmpfs (rw,size=10240k,mode=755) |tmpfs on /var type tmpfs (rw) |tmpfs on /tmp type tmpfs (rw) |devpts on /dev/pts type devpts (rw,gid=5,mode=620) |tmpfs on /dev/shm type tmpfs (rw) |root@triton1:/# mkdir -p /dev/.udev/db |mkdir: Cannot create directory `/dev/': Read-only file system
While: |root@triton1:/# cd /dev |root@triton1:/# mkdir -p .udev/db works as expected...
Has anyone else encountered this problem already? I've searched the archives but could not find anything related to this problem.
