The shared state cache (sstate-cache), as pointed to by
SSTATE_DIR
,
by default now has two-character subdirectories to prevent
issues arising from too many files in the same directory.
Also, native sstate-cache packages, which are built to run
on the host system, will go into a subdirectory named using
the distro ID string.
If you copy the newly structured sstate-cache to a mirror
location (either local or remote) and then point to it in
SSTATE_MIRRORS
,
you need to append "PATH" to the end of the mirror URL so that
the path used by BitBake before the mirror substitution is
appended to the path used to access the mirror.
Here is an example:
SSTATE_MIRRORS = "file://.* http://someserver
.tld/share/sstate/PATH"
