Format string bug in update-rc.d script

[Emanuel Bronshtein]

Binary package hint: sysvinit

/usr/sbin/update-rc.d and /usr/sbin/update-rc.d-insserv scripts have format string bug .

test case :
emanuel@emanuel-desktop /tmp>>touch bug%nf
emanuel@emanuel-desktop /tmp>>update-rc.d "../../tmp/bug%nf" start
Modification of a read-only value attempted at /usr/sbin/update-rc.d line 187.
emanuel@emanuel-desktop /tmp>>update-rc.d "../../tmp/bug%nf" remove
Modification of a read-only value attempted at /usr/sbin/update-rc.d line 82.

the problem is here :
printf STDERR "update-rc.d: warning: $initdscript missing LSB information\n";
printf STDERR "update-rc.d: $initd/$bn exists during rc.d purge (use -f to force)\n";

fix can be using print instead or add format %s to printf .
same bug exist in update-rc.d-insserv command from insserv package .
