The argument against Miklos' version is that there may be multiple
commands to execute while the fs is frozen.

Which is what a shell is for ;)

Yeah, weĺl, with your method I ca't tell a user to:

	# xfs_freeze -f /mntpt
	# xfs_db -r -c 'sb 0' -c 'p rootino' /dev/foo
	128
	# xfs_db -r -c 'ino 128' -c 'p core.format' /dev/foo
	core.format = 2 (extents)
	# xfs_db .....
	.....
	# xfs_freeze -u /mntpt

i.e. using the freeze to force all metadata to disk and
prevent it from changing while doing interactive debugging
of some problem.

	# run_freeze /mntpt /bin/bash
	# ...
	# ^D

It's the same, no?
