Colleagues,
I suppose at least some of you do not track -stable@ due to its volume.
Your thoughts?
Thank you!

I forgot to mention that it is ZFS-based.

ktrace'ing restore I've found that stat(".") on ZFS in my case returning
blksize=5632, which makes restore unhappy somewhere at
261- if (stbuf.st_blksize >= TP_BSIZE && stbuf.st_blksize <= MAXBSIZE)
262- fssize = stbuf.st_blksize;
263- if (((fssize - 1) & fssize) != 0) {
264: fprintf(stderr, "bad block size %ld\n", fssize);
265- done(1);
266- }
commenting lines 263-266 gives me working restore.
Any hints from now? It's not clear to me why we check this at all?
Thanks!
