I needed to do something about our shared sstate store and waded into
the sstate cache management problem as the existing script takes hours
to run over NFS (which for better or worse is where ours is). I've set
myself the problem of replacing the existing script with something
more extensible, understandable and performant.
I've got something which I believed was roughly right, but I'm ending
up with questions I can't answer when comparing the two outputs...
If I run the existing shell script against a tiny sstate-cache (on my
laptop) I get 420 duplicate files eligible for removal, if I run my
script I get 491, looking into the delta, I pick out things like
these:
$ find sstate-cache/ -name
sstate:libcap-ng:core2-64-poky-linux:0.8.3:r0:core2-64:10:*_populate_sysroot.tar.zst*
-ls

Which look to me like I should be able to delete the older ones, or am
I missing something? Trying to follow what the existing script is
supposed to do is challenging!
