Hi,
Summary:
I suggest that, for the "Which disk is your root disk?"'s question in
the installer, a logic should be added so that if a softraid has been
set up, then it should be used as default option (rather than the name
of the first physical disk available in the system, as is the case
currently, and which is the healthy default for all other use cases).
Background, details, discussion:
If you set up a crypto softraid, it will become a separate disk device
e.g. sd1 .
When reaching the "Which disk is your root disk?" question in the
installer, it will suggest the first physical disk available, normally
sd0 or wd0 .
Just in ase the user would be unclear that from this point and on, the
installation only should regard work with the softraid (sd1),
(because files will be installed to sd1 and installboot when commanded
to install to sd1 actually will install to sd0 thanks to its magic
resolving feature which figures out that sd1 is a softraid and hence the
boot code shouldn't be installed on it, but rather on the softraid's
parent drive, and accordingly it resolves which the parent drive is and
installs the boot code on that one instead - super neat but not yet
written up in any man page,)
then, it could be a good idea to simply prefill this question with "sd1"
(the softraid's device name) instead of sd0.
If the user mistakenly would go on with sd0 he'd wipe his softraid setup
and bring the system into an inconsistent state.
The counter argument to this suggestion would be that crypto softraid
anyhow only is for so advanced users that they should have the wisdom to
enter the softraid device's name (e.g. sd1) themselves already.
That counter argument would make much more sense as soon as the
installboot resolver thing mentioned above has been documented.
Anyhow so in either case this is just a convenience level feature.
Thanks,
Tinker
