I have discovered that using:
(cd /usr-b; tar -cp -xattrs -f - .) | (cd /usr; tar -xp --xattrs -f -)
OR
(cd /usr; cp -pR /usr-b/. .)
did not preserve the selinux attributes.
I have checked the attributes in /usr-b/lib/libsysfs* and
it has lib_t assigned to these files against the copied files
/usr/lib/libsysfs* and it shows default_t instead of lib_t.
This may mean that my entire /usr filesystem has improper
selinux attributes.
Can someone tell me how to copy the files from my original
/usr-b filesystem to /usr filesystem with the selinux attributes
intact?
