I have installed the pyxattr-0.4.0-2.el5 rpm and I am using the
rdiff-backup-1.2.8-1.el5.rf rpm on CentOS 5.
I have se-linux fully switched off but I would like to preserve the
se-linux extended attributes in the backup. I would like to restore
files with rsync, not rdiff-backup when necessary and so I need the
extended attributes to actually be stored as extended attributes and not
just represented in the rdiff-backup-data directory.
As a test, if I can see that rdiff-backup works on my root file system.
$ cd /root
$ rdiff-backup --include /etc/fstab --exclude /etc /etc test
$ ll -Z test
-rw-r--r-- root root user_u:object_r:etc_t:s0 fstab
drwx------ root root rdiff-backup-data
If I repeat this test on a mounted ext3 partition the selinux
attributes are missing.
$ cd /mnt/data
$ rdiff-backup --include /etc/fstab --exclude /etc /etc test
$ ll -Z test
-rw-r--r-- root root fstab
drwx------ root root rdiff-backup-data
Yet I can manually set the selinux attributes on this file. So the
mounted partition IS capable of storing the attributes.
$ chcon user_u:object_r:etc_t:s0 test/fstab
$ ll -Z test
-rw-r--r-- root root user_u:object_r:etc_t:s0 fstab
drwx------ root root rdiff-backup-data
Is rdiff-backup wrongly assuming that the target directory location
can't handle extended attributes?
