As discussed in the mailing list, this is a quick draft for a (imho) neat functionality: if there's an error connecting to a capsule, try to do a TXT query at _offline.$hostname (this is subject to change) and show the message to the user. It's a nice way to communicate to the user that a certain capsule is, for example, supposed to be offline in certain situations.

During safe_mode the fs process shouldn't open or unlink the crashed_file.

When enabled with the -S (or --safe) flag, prevent telescope from writing files to the disk.
