Hello,

I have round about 450 packages installed (without so called FreeBSD- 
snap files)
Then I typed the command pkg install -r FreeBSD-base -g 'FreeBSD-*'
and the FreeBSD- snap files were installed.
pkg info | wc -l shows me now round about 900 installed packaged.
I did try to get rid of the none snap files with pkg delete -af 
afterwards the
all files were deleted, the snap files too. The system was unusable.

Don't know what the FreeBSD- snap files are.
Don't know about experimental install.
Excuse me the stupid asks.

Can you give me some advices to this subject. How can I remove with "pkg 
delete" only the right packages.

Thanks
Manfred
