dump/restore and SElinux security context problem
[This was originally posted on fedora-list, and despite some helpful
answers, the problem still remains. --Kayvan]
Hi everyone.
I was trying to upgrade from FC4 to FC5, but my root partition was too small
to accomodate the DVD image. So, I had to resize some partitions. GNU parted
was useless in that task (see Redhat Bugzilla Bug 90894).
Finally, I used "dump" to create a snapshot of a filesystem, then, using
the FC5 DVD to boot into rescue mode, used "restore" to recreate it.
The problem: during the restore, for every file, I get messages like this:
restore: lsetxattr ./System.map-2.6.15-1.1833_FC4 failed: Invalid argument
This feels like it's related to SELinux. In fact, looking at
the restored files with "ls -Z", I see that they are all unlabeled.
If I don't use the rescue CD, and instead, on a running system where SELinux
is enabled, do the following:
1) setenforce 0
2) restore from the dump.
3) setenforce 1
Then, the restored files are in their correct security context.
How do I get this same result (files completely restored, along with
their extended attributes) while using the rescue CD?
My end goal is to be able to do a dump, boot into a rescue mode,
resize partitions, format new filesystems and restore the dump, and have
all files retain all their attributes (including their SELinux context
information).
Thanks for any answers.
