Re: dumpdev AUTO in rc.conf does not work

[Daniel Morante via freebsd-current]

Yes my fstab entry is:

/dev/gpt/swap     none            swap    sw      0       0

It looks though that this issue might only happen on arm64?  I tried to reproduce on amd64 without any luck.

Hello,

I am running 14.0-CURRENT using the snapshot from 2021-08-05.__ It looks
as if setting dumpdev="AUTO" in /etc/rc.conf has no effect on enabling
kernel crash dumps.

root@callisto:~ # sysrc dumpdev
dumpdev: AUTO

I have to manually enable it via dumpon even though it's set to AUTO in__
rc.conf

root@callisto:~ # dumpon /dev/gpt/swap
root@callisto:~ # dumpon -l
gpt/swap

Works for me if I set dumpdev to AUTO.

I ran '/bin/sh -x dumpon start' and it found the swap entry in /etc/fstab,
as expected.

Does your /etc/fstab entry for swap have the correct syntax?  Mine looks
like this:
/dev/ada0p5             none            swap    sw              0       0
