24.04 Noble New desktop installer skip Grub bootloader setup?

Asked by Peter Lee

The Ubiquity installer allowed the user to specify that no bootloader should be set up (at one time, it was a choice in the gui, later is specified by the --no-bootloader or -b option on the ubiquity command). There are situations where this can be useful or even essential in order to get a working installed system: see for example my bug report 2070279, and https://gist.github.com/volcanoauthors/c7c9480dc78f1ba55d589d2125db4832 for the troubles that buggy firmware can cause.

I can't see any obvious way to be able to skip Grub setup in the new ubuntu-desktop-bootstrap/subiquity installer. Is it possible? If not, then I'd strongly suggest that the facility be reinstated*: it's really too useful in edge-case scenarios to be dropped.

* eg by adding a "no bootloader" entry to the "Device for boot loader installation" list on the Manual Partitioning page
Also, the bootloader location could usefully be shown on the Review Your Choices page in any case.
