[gentoo-user] Stroppy perl-cleaner

[Peter Humphrey]

Hello list,

What is perl-cleaner objecting to here? It all seems pretty anodyne to me:

$ alias perl-cleaner
alias perl-cleaner='sudo perl-cleaner --all -- --ask --usepkg --jobs=3 --keep-going'
$ perl-cleaner

Your use of -- to supply extra arguments to emerge. It means you may be using unsupported options so if it breaks, the pieces are all yours.

Yes, I can read the words, Neil  ;-)  I just want to know whether it's 
safe to ignore the warning even when issued with such vigour. As I said, 
I can't see anything dangerous in the arguments I pass in the alias.

Those should be safe, none of your selected options change the final output.

Personally, I think the warning is going a tad overboard, but hey to
each dev his own

Nor can I. The warning is really saying you are using an
unsupported combination of options. Rather than saying they are unsafe,
it is saying they are not certain to be safe. The decision is yours, but
my reaction to the warning is along the like of "OK, whatever" and then I
do it anyway.

You are using something which is not recommended by developers, that is
'-- <extra portage parameters>', telling perl-cleaner to pass
additional package manager parameters, not sure why is not recommended,
but it warns you, also in 'perl-cleaner --help' or man page it says it
is not recommended to do that. 

There is probably case when you can do
something wrong, but also it can be safe too passing some parameters
which don't affect build like '--ask'. 
One case which may be problematic (or not, just guessing) is --jobs=N,
what will happen if one perl module depend on the other, and they are
building at the same time?

Then portage will sort them out according to dependencies, as usual.
