Subject: [PATCH] Accepting request 336568 from
 home:favogt:branches:Base:System

Please review this thoroughly, I've never looked at rpm's code before.
(I revoked the last SR as it did not contain a required change I forgot to commit)

- Add nfs-blocksize-free.patch:
  * Blocksize of NFS shouldn't be used directly
- Fixes bsc#894610 and bsc#829717

+Subject: [PATCH] Blocksize of NFS shouldn't be used directly
+
+RPM uses the blocksize to calculate whether an RPM
+can be installed on the system. For NFS this fails
+for e.g. glibc-locale as it has many small files,
+which rpm counts as one block. As huge NFS block
+sizes (>= 1MiB) are common, this makes glibc-locale
+roughly 7 GiB in installed size.
+
+As a workaround, if the NFS block size is > 4096,
+assume 4096 and scale the count of free blocks
+accordingly.
+
+See also RH bug 847960
