Why is `openin_any = p` restricting access to packages in TEXMFDIST?

Probably, it is due to changes in latex.

In general, probably, files found internally by kpse

can be read even in the case openin_any=p.

However if full path etc. are found in sources or command line,

some files may be rejected to read by kpse_in_name_ok():

latex sample2e.tex

works, however

latex full_path_of_sample2e.tex

does not work.


Best,
