No, the bug report in Debian's bug tracker that I was referring to is 
not filed against Syslinux-related packages. The fact that there was no 
maintainer for Syslinux-related packages is just an additional 
complication in this matter. IOW, I am not referring to that bug

I stand by my prior statements.

I took my own time to provide feedback to a specific developer in 
Debian, after seeing his own bug report. The reply I got was that he is 
not interested in implementing the workaround for Syslinux in the 
relevant Debian package (which, again, is not the Syslinux-related 
packages). Moreover, Debian users have brought up the specific matter / 
culprit, even in the same bug report (and not only there), and they 
received no reply.

I usually try to be clear and specific. Considering the lack of 
interest in supporting Syslinux (in so many levels), at this time I 
will not be providing details related to Debian's bug report. Yet, it 
is important for me to repeat that Debian is not alone in this regard.

Adding a link to the "Filesystem" page of the Syslinux wiki? The same 
might help in other bug reports, and maintaining/updating the 
package(s) might help too (so, thank you for adopting it).

Aha! Finally the most important matter, especially in this Syslinux 
mailing list. If the proposed patch is tested and feedback is reported 
back here, then perhaps we'll finally see some relevant action. The 
proposed patch, by Paulo:


Similar reactions (i.e. no relevant reply) can be "seen" regarding:

_ updating the gnu-efi submodule (small email thread):



_ Not enough room for program headers (aka binutils 2.27+ screwing 
Syslinux build):


Those are just a few examples.

Thank you for adopting the Syslinux-related packages in Debian.
