Hmm. On an aarch64 machine I could not use:
pkg install freebsd-gcc6@aarch64
after my poudriere bulk run. I had to use:
pkg install freebsd-gcc6
So there are places where the two notations are not equivalent,
despite aarch64 being listed first for freebsd-gcc6's FLAVORS.
One has to know what the FLAVORS list starts with in order to
know what to type in some contexts; one can not just always
type in the @flavor notation.
This was for:
# pkg -v
1.12.0
It reported:
# pkg install devel/freebsd-gcc6@aarch64
Updating custom repository catalogue...
custom repository is up to date.
All repositories are up to date.
pkg: No packages available to install matching =
'devel/freebsd-gcc6@aarch64' have been found in the repositories
The file for the poudriere bulk -f listed:
devel/freebsd-gcc6@aarch64
(despite the context being aarch64 in the first place).
