Beware that export mangles some characters special to POSIX shell.
This is more reliable and shorter (also by using \K and no capture):
myopt='bla' perl -i -pe
's/^GRUB_CMDLINE_LINUX_DEFAULT=\".*\K(?=\")/ $ENV{myopt}/' /tmp/grub
I agree with the general point that this feels too tiny and narrow
purpose for a Debian package.
I do recognize, however, that oneliners like the above are easy to do
wrong, and that's scary when it is the bootloader configuration you are
messing with.
Would it perhaps be interesting for you to generalize your script to a
"grub-set-bootarg" script which adds _any_ option to grub, or replace
its value for an option already declared)?
You could then propose the package maintainers of grub to include that
script with the grub package.
If grub maintainers reject your proposed script, you might consider
generalizing even further to a "configfile-set-arg" script that first
tries to detect syntax, and for a syntax recognized does the surgery.
You could then propose to have that script added to package moreutils.
