comment What are some ways to update symlinks when the dir they point to are changed?
maybe have a look at tagstore.org anyway you should probably think about writing a software helping you manage your data. you could also look into knowledge management systems or document management systems…

it depends exactly what you need/want. It sounds like there is a bigger issue here at play, like about deployments, configuration management etc. Maybe write a small application which does what you want

comment Can I create a bootable distribution backup
why is using a live cd not an option? most livecds allow you to have some kind of persistency where changes will be written to a blockdevice

Try to login via ssh and use expect or use some ssh library or connect to your kvm servers/vms and try to login via the serial console (again via expect).

comment How to build space separated, escaped full paths of files recursively matching glob?
if you quote an argument the program does not see or recognize this, e.g. /home/user/a\ b.csv is the same as "/home/user/a b.csv" for the program (if you enter it in a shell)

comment Which distributions can have a network installation started from a floppy?
this is why this is a comment and not an answer, and pxe boot is a solution to the problem (install a system without usb/cd/hdd) and is covered in the documentation of the distributions. using floppy disks for such tasks is unnecessary and nowadays not many distributions support floppy disks.
