[Bug 1786821] Re: pam.7.gz is a symlink to PAM.7.gz . This does not work for caseinsensitive filesystems e.g. Windows Subsystem for Linux

[Balint Reczey]

IMO this issue is fixed in newer Windows builds, I suggest upgrading
your underlying Windows system to avoid having problems with case
insensitivity of the file system.

Since the PAM man page is present for long years and capital letters in
man names are not exactly rare I don't think this should be fixed based
on just the presence of the capital letters:

$ apt-file search man/man | grep '[A-Z]' | wc -l
46066

If there were only a few files present with both uppercase and lowercase
names I'd lean towards fixing them, but there are ~3k file pairs in
bionic:

$ for i in $(apt-file search / | cut -d' ' -f2 | sort | uniq | tr '[:upper:]' '[:lower:]' | sort | uniq -c | grep -v '^ *1 ' | awk '{print $2}' ); do apt-file search -i $i; done

firejail-profiles: /etc/firejail/Cyberfox.profile
firejail-profiles: /etc/firejail/cyberfox.profile
firejail-profiles: /etc/firejail/FossaMail.profile
...

It is not feasible to fix all of them in Ubuntu, maybe the ones in main
but IMO one should update Windows to make it support case sensitive
operation.

Title:
  pam.7.gz is a symlink to PAM.7.gz . This does not work for
  caseinsensitive filesystems e.g. Windows Subsystem for Linux

Status in pam package in Ubuntu:
  Won't Fix

Bug description:
  The package libpam-runtime contains a symlink pam.7.gz -> PAM.7.gz in
  ./usr/share/man/man7 and this doesn't work in Windows Subsystem for
  Linux since Windows has a caseinsensitive filesystem.

  On ubuntu 18.04 this PAM.7.gz exists too. I know it's not a linux
  centric issue. But why libpam-runtime is using Uppercase and symlinks
  anyway? Other packgages in man7 just use lowercase, and this is what
  I'm expecting.

  Hopefully you can fix it.
