SELFAUTOPARENT for redistributors

[texlive at schoepfer.info]

Hi,

some scripts are failing here, as these search for SELFAUTOPARENT and 
get '/', e.g.

bbl2bib:    chomp(my $TLMaster = `kpsewhich -var-value=SELFAUTOPARENT`); 
# TL root
biburl2doi:    chomp(my $TLMaster = `kpsewhich 
-var-value=SELFAUTOPARENT`); # TL root
ltx2crossrefxml:     chomp(my $TLMaster = `kpsewhich 
-var-value=SELFAUTOPARENT`); # TL root
bibzbladd:    chomp(my $TLMaster = `kpsewhich 
-var-value=SELFAUTOPARENT`); # TL root
bibdoiadd:    chomp(my $TLMaster = `kpsewhich 
-var-value=SELFAUTOPARENT`); # TL root
bibmradd:    chomp(my $TLMaster = `kpsewhich 
-var-value=SELFAUTOPARENT`); # TL root
pedigree:    chomp(my $TLMaster = `kpsewhich 
-var-value=SELFAUTOPARENT`); # TL root

As SELFAUTOPARENT seems to be hardcoded, i tend to fix this by replacing 
SELFAUTOPARENT
with TEXMFROOT for these scripts.

Is there a better fix for redistributors? Would something break if 
upstream packages would
change to TEXMFROOT?

Thanks,

Johannes
