#1233 Issue closed: ReaR does not sufficiently error out if mandatory stuff is missing¶

At least sometimes "rear mkbackup/mkrescue"
does not sufficiently error out if mandatory stuff is missing.

I think when mandatory stuff is missing (e.g. parted not installed)
ReaR should error out early with a meaningful error message
than to blindly proceed until it errors out at an arbitrary later place
with an unexpected error message, cf.
https://github.com/rear/rear/issues/1210#issuecomment-285003858
and

In general regarding "error out early" see also

FYI:
REQUIRED_PROGS works as expected.
I have in local.conf

REQUIRED_PROGS=( "${REQUIRED_PROGS[@]}" qqq )

and "rear mkrescue" errors out:

# usr/sbin/rear -d -D mkrescue && echo OK || echo FAIL
