Bug in Solaris 10 cpio when restoring ACL’s.

Solaris 10(Sparc) cpio returns errors “cpio: aclfromtext failed:
Unrecognized entry type” or similar when the number of acl’s exceeds
260 on directory/file entries, or spans more than one 8192 buffer for
the ACL header.

This is reproducible when copy in (-i) or listing (-it) table of
contents using the caps “P” “Preserve ACLs” switch.

CPIO copies out (-oP) without errors!

The above error exists at patch revision 140914-01 and 140914-02

Anyone else experiencing this?

I suspect not! Your usage of ACLs seems more than a little extreme.
Perhaps your needs are extreme but I'm inclined to think that there must
be a better way to do whatever you are trying to do.
