comment allowing timeouts for commands that have no timeout option, where `IFS=$'\n'`
@DanielBeck I'm looking now but can't see what you mean – sorry. I'm easily confused with scripts, and generally a bit dyslexic about learning things … I need some hand-holding here to avoid learning the wrong lessons …

comment Understanding mount option nodev and its use with USB flash drives
With ZEVO Community Edition 1.1.1, import is dynamic (automatic) and it seems that the default is to mount automatically without nodev. Neither the import nor the ZFS mount requires authentication … let's see how things fan out in the ZEVO area.

comment Understanding mount option nodev and its use with USB flash drives
This is a great answer – thanks. If I understand things correctly, another question arises … in the ZEVO support forum: Why are ZEVO ZFS mounts without the nodev option? (At the moment I have no spare USB hard disk drive to give to HFS Plus alone.)

comment Handling whitespaces in the name of a ZFS dataset in a shell script
Alongside the accepted answer below, with this answer (to How can I take the output of a shell script and place it in a file on the command line?) I realise that for the output to file – for the append – I need >> (not &> or &>>). In feedback to Apple I asked for sysdiagnose to be added to Apple Open Source – if this happens I'll make public my other changes to the script, most of which are unrelated to ZFS.

The question as originally asked is answered. The output to file criterion can be separate.

comment Handling whitespaces in the name of a ZFS dataset in a shell script
/bin/bash did not workaround. I edited the question to include more context, and to show more clearly how I'm experimenting based on this answer. Partial success. I could be making some very basic mistake somewhere! Thanks …
