[rancid] MikroTik missed cmd(s): system package print detail without-paging

[IT-Info]

Hi Heasley,

I appologize, but how do I apply this patch?  Does this need to be appended to the bin/mtlogin.in source file and then recompiled?  Can you clarify for me?

Thanks,
Brian

These MikroTik devices are those that have been replaced due to failure or other reason.  I delete the key in .ssh/known_keys, the new key is added upon next run, but then this error appears.  Since we've replaced many MikroTiks over the past 6 months, the list of MikroTik devices with this issue is growing - I've got about 20 now.

This issue is similar, but I don't know the solution and I can replicate it after physically replacing a MikroTik device.

Would you try this patch?  please lmk if it fixes the problem.  if it doesnt,
perhaps you can give me remote access to one.
