Whats about -r' flag for uninstall?
That only works for the dependencies. So, for example:
foo depends on bar
..then:
pkg uninstall -r bar
Would remove foo and bar.
But, pkg uninstall -r foo, would only remove foo.
Really? That seems totally backwards to me based on all the other
package managers I've used that could uninstall dependencies.
If I install foo and bar isn't installed then both foo and bar get
installed. If I uninstall foo (using -r) and bar isn't a
dependency
for
anything else I'd expect bar to get uninstalled as well. If both
foo
and bar are installed and I uninstall bar I'd expect a warning
saying
that bar is a dependency of foo.
Why does it work the way you describe? I'm not really seeing the
logic.
I didn't implement it, so I can't tell you, but that's the way it is
documented to work, and the way it works:
In the case of uninstall, the -r option will recursively
uninstall any packages which are dependent on the initial
package.
Before I forget, the other reason would be that, currently,
recursion in
the other direction would be fairly useless.
For example, a recursive removal of Apache would eventually end up
removing all packages on your system. How does one know where to
stop
the recursion?
And this is the disconnect I'm seeing. The recursive removal is
working
backwards to any other system I've ever seen or used. It's operating
bottom-up instead of top-down.
From what I've seen it works bottom-up in other systems, and in ours
it works top-down, but perhaps I'm upside-down right now ;)
pkg uninstall -r Apache right now wouldn't do the same thing it would
on another system.
baz and tells me that I'm potentially breaking foo. Going backwards
(up
the chain) just doesn't make any sense to me. Using the current
As far as I'm aware, that's exactly how it works on other systems.
In other words, if I recursively remove foo, which depends on bar, foo
and bar get removed.
implementation, I have foo which depends on bar and bar which
depends on
baz. I say pkg uninstall -r bar. So bar and foo get uninstalled,
what
about baz? How/where does it get uninstalled?
Right, that was exactly the question, and the next question is, how do
you know when to stop?
