automating chroot and mount/unmount

Thank you for the info!
Hey! maybe there is a work-around?...
Perhaps I should describe the goal? That always seems to help.
The motivation for chroot'ing is that I am not familiar with another way
to run mkinitrd. Honestly, I am surprised there is not -root option such
as with the rpm command or tar's -C, etc. If I could specify my root
file system on the command line then I would not need to chroot to
run mkinitrd.
So, to answer your question, the reason I believe I need to unmount, is
because after chroot exits, I archive the entire file system with tar.
If I do not unmount, tar complains with errors that the file system is
mounted or some such message. I can set up the situation again and
fetch the exact error message.
Through experience, I know that if I unmount properly, I avoid the
tar error when creating the tar archive.
Cheers,
:-D

copyfs-mount
COPYFS-MOUNT(1) User Commands COPYFS-MOUNT(1) NAME
copyfs-mount - mounts a versioned file system SYNOPSIS
copyfs-mount version-directory mount-point DESCRIPTION
This script lets you mount a CopyFS file system. version-directory is the directory where the files and version information will be stored by CopyFS. When using CopyFS for the first time, copyfs-mount will create the required files in the version-directory before running copyfs-daemon. mount-point is the directory where the copyfs file system will be mounted. This is where the users will have access to the files. If you want to mount a CopyFS at '/mnt/fs', whose version directory is at /var/versions, you would use: root@host# copyfs-mount /var/versions /mnt/fs To unmount it, simply do: root@host# umount /mnt/fs As you would do for any other filesystem. You can also allow an ordinary non-root users to mount and unmount CopyFS filesystems provided that the user is added to the 'fuse' group. Ordinary users will be able unmount the filesystem, using the fusermount command: $ fusermount -u mount-point AUTHORS
CopyFS was created by Thomas Joubert and Nicolas Vigier <boklm@mars-attacks.org> LINKS
