Nicer error message when guble is run as unprivileged user
fwilhe opened this issue · comments
When I try to run guble as user on linux (fedora) (built using go get, not in a docker container), I get this message:
$ guble --log-info

The problem is clear from that message, but I would prefer to catch this case and output a nice message like
guble needs to be run as root because xyz
This would improve the first experience using guble.
Also, this should be mentioned in the readme, I think
Thx, good point!
I'll fix it.
Fixed in master.
