[rsbac] Gentoo / RSBAC / Encrypted Root / Unmount fails

[Michael Decker]

	Hi,

could somebody help me to solve this problem. I try to encrypting whole
root device by doing this howto:


So my booting fails caused by an unmount error.

On booting an own created initrd will be started to open luks encrypted
filesystem, so this last steps of linuxrc-script [2] fails (on umount
command):

	--- SNIP ---
pivot_root . initrd

# Start init and flush ram device exec
chroot . /bin/sh <<- EOF >/dev/console 2>&1
umount initrd
rm -rf initrd
blockdev --flushbufs /dev/ram0
exec /sbin/init ${CMDLINE}
EOF
	--- SNAP ---

So I get this error:
	--- SNIP ---
EXT3 FS on dm-0, internal journal
EXT3-fs: dm-0: 1 orphan inode deleted
EXT3-fs: recovery complete.
EXT3-fs: mounted filesystem with journal data mode.
0000000037|rsbac_free_dat_dentry(): freeing dat dir dentries
0000000038|do_umount() [sys_umount()]: umount failed -> calling
rsbac_mount for Device 01:00
	--- SNAP ---

I've run the kernel with this options:
	--- SNIP ---
Kernel command line: root=/dev/ram0 rw init=/linuxrc rsbac_softmode
console=ttyS0,57600 console=tty0
	--- SNAP ---

Is this a RSBAC problem? Do I have to modify the script [2]? Perhaps
could somebody give a suggestion?

Best regards,
	Michael Decker
