stems from  #248140
 base-files: user private groups concept requires umask 002 to work


Please reasign to base-files if/when umask should be changed.

The question is if possible copying to systems without UPGs while
aliasing to "scp -p" warrants to disable the user private group benefits
for all debian systems by default.

but the user may have scp aliased to "scp -p",
in which case the permissions of the original file take precedence,
so, as I said, I prefer to follow the principle of least surprise here.

Hi,

        I don't think that this is a policy matter. It is not as if
 the individual user of local admin can't change the defaults; and
 having the umask remain at 022 is safer be default (as in the case
 mentioned in the bug report).
