That is very strange. For aufs2 and later, mount.aufs is written in C, so it should be a binary. Actually it was a shell script in aufs1 era. I am afraid your mount.aufs is TOO OLD. I'd suggest you to use the correct version of aufs2-util. You can get them via GIT. See http://aufs.sf.net in detail. But I have to warn you. As you might know, aufs2.x for linux-2.6.32 is obsoleted now. > The C runtime environment is the same on all. > Mount.aufs is statically linked for Rhel 6.3. ?? I am a little confused. Do you mean mount.aufs on your Rhel 6.3 is a C program? Then comparing the behavioud of it on 6.1 and 6.3 never mean anything. Anyway I'd suggest you to create /dev/tty on your 6.3 first. (But I am not sure it will solve all problems since you may meet another issue) > ccl:warnings being treated as errors > fs/aufs/super.c: In function au_statfs_sum > fs/aufs/super.c:325: error: passing argument 1 of vfs_statfs from > incompatible pointer type > include/linux/fs.h:1867: note: expected struct path * but argument is of type > struct dentry * > > This same error is also in super.c function aufs.statfs. > > This is the fs.h header file: > Rhel 6.1 kernel: linux/include/linux/fs.h:extern int vfs_statfs(struct dentry > *, struct kstatfs *); > Rhel 6.3 kernel: linux/include/linux/fs.h:extern int vfs_statfs(struct path > *, struct kstatfs *); It means Rhel 6.3 kernel has backported things from later kernel, and the interfaces changed. As you now, all aufs releases are for linux-x.y.0. Aufs2.x-32 is for linux-2.6.32.0. If you want to build aufs for Rhel 6.3 kernel, then you need to backport things from aufs sources for linux-2.6.33 and later. J. R.
