Dear Maintainers,

While working on my customized Debian installer (DI) I noticed that the
DI INITRD from the current "debian-11.3.0-*-netinst.iso" files (at least
for AMD64 and ARM64 architectures) contains probably obsolete source
code in the following file:

- In the "./bin/mountmedia" file from the "mountmedia_0.25_all.udeb" at
least the lines 31-35 could be obsolete, because according to
"https://bugzilla.kernel.org/show_bug.cgi?id=7875" the mentioned bug was
fixed ages ago.

My customized DI seems to work normally without the mentioned source
code. But I did not test mounting of any floppy media during
installations and my DI also has various other removed and modified
files, so verify/test what I found if needed.

Best Regards
Jmkr
