Aw: Re: Defining quota on /home

[c.monty]

I'm sorry.
Of course the line
0/279         1.79GiB      1.79GiB    150.00GiB         none
is correct.

The issue is with this line:
255/279       1.79GiB      1.79GiB         none         none
I didn't define a quota like this.

THX

This is default quota group created automatically for each subvolume. Or
do you mean 255/279?

I don't know if it's the 4.4 kernel, or the tools, but I observed the
same extra quota group whenever quotas were enabled on Ubunut 16.04 system.

 I didn't give it much though, as it didn't hurt anything to have an
extra higher level group.  (quotas and snapshots on that kernel were
effectively mutually exclusive features in any case.)
