Comment 10 for bug 1868138

as noted above, these configs have been in place " on a long-time-in-production Ubuntu 1804LTS server instance"

the configs have been in-place, with line breaks, for years. across countless upgrades, on ~100+ servers. including grub* packages.

upgrades have ONLY started failing with most recent upgrades.

could we have been 'just lucky'? sure. that in itself is disturbing & being investigated. likely to be migrated away from -- as these configs, with line beaks, are NOT a problem _anywhere_ 'else'.

is my specific config relevant? not if you accept,
