Bugzilla Bug 214619

Doing some work on my system having most of my system compiled with -pg,
Portage got to spewing collisions between all the gmon.out files that got
generated. Using INSTALL_MASK is insufficient, because the install mask
handling generates more gmon.out files ;-).

Could we please have a variable to pass custom options to the tar invocation in
dyn_package? This lets me pass --exclude as well as -X and anything else useful
(maybe options to preserve xattrs).

Maybe PKG_INSTALL_MASK (which is already supported) will solve your problem
with the gmon.out files. Anyway, I'll do a patch to implement
PORTAGE_BINPKG_TAR_OPTS.

INSTALL_MASK/PKG_INSTALL_MASK aren't sufficent because it needs full pathes to
the files - AND the find invocation in install_mask() leaves gmon.out file of
it's own, because it runs from ${D}.

Changing it to run from ${T}, and changing the dyn_package tar to run from ${D}
as well might also be an improvement.

Okay, preinst_mask() and dyn_package() (which process INSTALL_MASK and
PKG_INSTALL_MASK) are both called from ${T} now. Also, preinst_mask() is called
after all other functions so that INSTALL_MASK can be used to remove all
gmon.out files.

Here's how install mask works:

set -o noglob
for no_inst in ${install_mask}; do
        set +o noglob
        rm -Rf "${root}"/${no_inst} >&/dev/null
        find "${root}" -path "${no_inst}" -exec rm -fR {} \; >/dev/null
done

It seems like you should be able to use INSTALL_MASK="gmon.out */gmon.out" to
match all gmon.out files anywhere in ${D} (the first would work via rm and the
second would work via find -path).

PORTAGE_BINPKG_TAR_OPTS implementation and $PWD tweaks

This is fixed in 2.1.5_rc1.
