Hey Ged,
Thanks for getting back to me.
I'll overlook the sarcastic cynicism - it's probably healthy (and I'm partial 
myself). As to xargs, I wanted a config file rather than command line but 
clamd/clamdscan raises more complications around user and selinux permissions 
etc so xargs seemed, ironically, the simplest/quickest way forward.

Dunno why / and /home being on the same fs didn't spook me - I suppose I just 
accepted it as a Fedora thing as Fedora's not my usual distro - in any case 
thanks for highlighting it and prompting me to find 
https://unix.stackexchange.com/q/621771/295876 ... which says this is normal 
for Fedora now - not something to be concerned about.
It would seem that clamscan should be scanning /home but just doesn't take this 
Fedora/btrfs situation into account ( its a std Fedora 35 WS install albeit as 
a VM )
If this is the reason then that's technically a bug I'd say - there are 2 
legitimate dirs to scan.
Any thoughts before I post on github ?
Bob.

Kinda creative and unnecessary, I think, to use xargs in this way and
the result goes against the 'man' page for clamscan although I guess
you'll get away with it.  Normally I'd prefer to show full pathnames
for something like this, and keep the commands as simple as possible.
You don't need quotes in your regexes in clamscan.conf, they'd only
be necessary if there were things like space characters in them.

If we are to believe what you've pasted there then you have /dev/vda2
mounted twice, once on '/' and once on '/home'.  Why it seems to think
that you have different amounts of space 'Used' and 'Available' on the
partition when it's mounted on different mount points I don't know but
it feels like something's badly messed up and you should sort that out
before you do anything else.

I think it's telling you - the partition is mounted twice and it's a
little concerned by that.
