This may seem to be a valid idea, I have such an old machine with
linux distro which is 7 years after end of life. A newer distre
requires more RAM but there are no slots for more RAM in this machine.
Will TL contain i386 binaries for after-end-of-life distros with
obsolete versions of glibc? If not, I can either use the historical TL
2011 or compile from sources anyway and hope that I will be able to
compile it with obsolete gcc and obsolete glibc.

On one conference I received proceedings on a cheap USB stick. I was
never able to read anything from it. I tried to use it just as a USB
stich and found that it does not work at all. I would never recommend
cheap media. (Fortunately the proceedings could be downloaded from the
web of the conference.)
