symlinks not unpacked?

[jwaldmann]

I have a case where I think that symlinks are not unpacked. Cf. https://gitlab.imn.htwk-leipzig.de/autotool/all/issues/18

But it says here that it should work: https://github.com/haskell/tar/blob/028f2813d14380da3d99ac0b306b3cbb13731e56/Codec/Archive/Tar/Unpack.hs#L46

I built this keter bundle manually (tar czfv $KET $APP static config).

Even when I use --dereference when creating the archive, unpacking (via keter) does not work,
while it does via the command line.

I guess I should report this to the haskell-tar project.

I thought this was a bug in haskell-tar, an indeed there is some bug, but keter's behaviour is also wrong (or underdocumented) here? It just ignores any non-normal entries:

keter/Codec/Archive/TempTarball.hs

Line 86 in 1b10ffa

It seems that even with --dereference, gnu tar does not simply copy the target file, but does something different.

I got it working by adding the --hard-dereference option.
