I will gladly apply your patch but I think it's time to clean up the
mess with this:

This kind of duplication is just ugly. I looked around and saw this:
$ grep -r -E 'functions|9990-initramfs-tools.sh' components/
components/9990-initramfs-tools.sh:# Override maybe_break from scripts/functions
components/9990-initramfs-tools.sh: . /scripts/functions
components/9990-initramfs-tools.sh:# Override panic from scripts/functions
components/9990-initramfs-tools.sh: . /scripts/functions
components/9990-fstab.sh: # FIXME: stop hardcoding overloading of initramfs-tools functions
components/9990-fstab.sh: . /scripts/functions
components/9990-fstab.sh: . /lib/live/boot/9990-initramfs-tools.sh
components/9990-misc-helpers.sh: # the output of setup_loop is evaluated in other functions,
components/9990-netbase.sh: # FIXME: stop hardcoding overloading of initramfs-tools functions
components/9990-netbase.sh: . /scripts/functions
components/9990-netbase.sh: . /lib/live/boot/9990-initramfs-tools.sh
I have the feeling that all those problematic include are no longer necessary
nowadays because we first source all the files and then we execute functions
in the expected order. My review has not been thorough but can you try to remove
all those include and see if things still work?
/script/functions is already sourced in backend/initramfs-tools/live.script
so it should not be required to have it in the components, right?
BTW, I merged all you other patches. For the future, please send patches
as merge requests on the salsa repositories.
The only correction I made in multiple places is replacing "${VAR-foo}"
with "${VAR:-foo}". This gives a default value also when the variable is set
to an empty value.
Cheers,
