Subject: set_flags_from_control: remove function
X-Git-Url: https://git.librecmc.org/?p=oweals%2Fopkg-lede.git;a=commitdiff_plain;h=07f3b022c1cf6bcafe87f083ef2482eb7a8ec701

set_flags_from_control: remove function

During installs, install_data_files calls set_flags_from_control to
capture the case where fields, such as "Essential", are present in the
package control file but are missing on the Packages file. This
operation is expensive (re-parses the control file) and is catering to a
case that should not be supported on the first place.
