Can you explain why you must use abs_srcdir here, and what is special
about checkinstall that the absolute directory name must be used with
it?
I had the same error as in the stackexchange
```
Compressing *.el etc. ...
gzip: ../etc/publicsuffix.txt: No such file or directory
make: *** [Makefile:571: install-arch-indep] Error 1
**** Installation failed. Aborting package creation.
```
When I tried to debug, I found that the `pwd` is on `/usr/local/share/emacs/28.2/lisp` at this step with checkinstall.
I thought it must be another cd that is not reverted (cd -) but did not find it, using abs_srcdir here did not look bad either.
Thanks
