Solved help.common, boot flags, safe boot and nextboot(8)

[Cath O'Deray]

Through GitHub, I found what I need I thought I needed at <https://github.com/freebsd/freebsd-src/blob/main/stand/common/help.common>.

What's the normal way of accessing this help content?

 

[tingo]

Using the help command from the loader prompt. Or are you asking about something else?
FWIW, many (most?) of those commands are documented in the loader(8) man page too.

I was looking more at things such as:

set boot_single

– and the bigger picture (I changed the title of this topic) was wondering about boot flags, which I now see at boot(8).

As far as I can tell, there's not a boot flag for safe mode. True?

The wish is for safe mode to be set with nextboot(8).

True. That is because "safe mode" is not a single setting; it is a few settings that need to be set. If you are interested you will need to check out the lua scripts used in the boot loader. Eventually, you will find the function core.setSafeMode in the file /boot/lua/core.lua it shows the settings that needs to be changed.

I expect <https://github.com/freebsd/freebsd-...dbb712b68aec6841c958abae723b17761e83887ee2R79> to be particularly useful with regard to comment 7 under FreeBSD bug 254412 - emulators/virtualbox-ose-additions - Boot time crash - Sleeping thread owns a non-sleepable lock
