Description of problem:
rpm ignores the immutable attribute of files in an ext2 filesystem,
which causes the transaction to fail.  Instead, rpm should check
the immutable attribute during transaction setup.  There should
be a command-line option to override [and replace] the attribute,
or to query the user interactively.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. /usr/bin/chattr +i foo   # any file that will be replaced
2. rpm -Uvh foo.rpm
3.
	

Actual Results:  No checking in advance; rpm attempts the transaction.
Abort with EPERM; transaction failed.

Expected Results:  rpm should detect the problem during transaction setup,
and either temporarily set -i, then install, then set +i;
or give a message, then query the user.

Additional info:  Usually encountered during install or upgrade,
such as bug #64671, where the symptoms look like a problem in anaconda.
